Question: Nigeria's President Muhammadu Buhari has finally signed into law a budget for 2016 after months of wrangling.

He had refused to approve the 6.08tn-naira ($30.6bn; Â£21bn) budget amid claims of mismanagement and kickbacks among the officials who drew it up.
The budget triples capital expenditure in Nigeria.
Some 34 projects will get extra spending to help revive the economy, including improvements to power, health, and transport.
"It is a great pleasure to sign the budget. It is a serious article of faith for the Nigerian people," the president said at a ceremony.
"The signing of the budget today will trigger concerted efforts to reflate the Nigerian economy, a key element of which is an immediate injection of 350bn naira into the economy by way of capital projects."
The budget is based on an oil price of $38 per barrel, slightly below the current global market rate of just over $40.
Mr Buhari delayed signing the budget after finding errors in the spending programmes. The former military head of state, who has embarked on a widespread anti-corruption campaign since taking office last May, has claimed some lawmakers removed and replaced spending proposals.
Delays in approving the expansionary budget have added to Nigeria's economic problems of slow growth and high inflation.
In his address, Mr Buhari said Nigeria was "experiencing probably the toughest economic times in the history of our nation".
The government is hoping to diversify the economy, produce more food, revive manufacturing and generate employment to help boost growth.
Infrastructure development is also needed, particularly in roads, housing and power supply for Nigeria's 180 million people.

The 74-year-old leader, who has been out of the country for two weeks, was expected to return to Abuja on Sunday.
An official statement said he had been advised by doctors to await the results of a series of tests.
However, it did not say how much extra time would be needed.
There was also no mention of what the medical checks were for.

Nigeria's Buhari 'broke promise to end medical tourism'
The main opposition People's Democratic Party (PDP) has called for more transparency about the president's condition.
The failure of President Buhari to reveal the exact length of the additional medical leave in London is worrying many Nigerians.
There have been rumours about the president's health since he left the country two weeks ago.
He officially handed over affairs of the state to the Vice-President Yemi Osinbajo, a move commended by some experts as a sign of respect to the constitution and the rule of law.
Although things are running smoothly on the surface since Mr Buhari's departure, his continued absence might not be accepted wholeheartedly by some because of the country's worsening economic crisis.
After the first medical trip to London, Mr Buhari was heavily criticised by a leading health professional who felt that the president should have stayed and sought treatment at home.
Dr Osahon Enabulele, vice-president of the Commonwealth Medical Association, said it was a "national shame" that Mr Buhari had gone to the UK when Nigeria had many competent ear, nose and throat (ENT) specialists, as well as a National Ear Centre.
Health Minister Osagie Ehanire said Nigerians spent more than $1bn a year on medical tourism, an amount the present government has promised to reduce.
It is not clear how much Mr Buhari's treatment will cost and who will pay for it.  But as the number-one citizen, the state is expected to look after his wellbeing.
However, many Nigerians would not be happy if they realised how much such medical trips dent the country's already depleted foreign reserves.
Analysts say that Mr Buhari's extended leave could further erode confidence in his administration which is already under pressure due to a weak economy and the conflict with Boko Haram Islamist militants in the north-east of the country.
The country is currently suffering from its worst economic crisis in years, following a sharp fall in the price of oil, its major export.
Businesses and investors complain that the government's handling of the currency exchange rate has made a bad situation even worse, and there have been demonstrations against the lack of jobs and high inflation.
Some Nigerians are particularly anxious about the president's health after one of his predecessors, Umaru Yar'Adua, died in 2010 after several months of medical treatment in Saudi Arabia.
During that time, very little information was made public about his condition, leading to a political limbo in the country.
It is the second time in less than a year that Mr Buhari has sought medical assistance overseas.  Last June, he spent nearly two weeks, again in London, for treatment for an ear infection.
In Abuja, where some of the protests against government policies have been taking place, demonstrators used the occasion to voice their concerns.
One woman complained: "We are completely in the dark."
And a lawyer added:   "Anybody can fall sick but when a president falls sick, it should not be a confidential matter."
Nigerians have been giving their reaction on Twitter too and have commented on what they see as "double standards" over the issue of medical tourism:

Question: The 66-year-old Fields twins, from Missouri, have lived together all their lives - now they are even closer after sharing their skin.

Represent the news to retrieve its missing first sentence

Marian Fields had an aggressive and very rare form of skin cancer, which left her with large, open wounds around her backbone following multiple operations and radiation treatments.
She was beginning to lose all hope of recovery after plastic surgeons in the US refused to take on her case because of the size of the wound.
But her identical twin sister Mary Jane provided the solution.
"There was never a moment of hesitation when the option to donate skin and tissue was a possibility," Mary Jane said.
"I had what she needed. We are two bodies with one soul. She is my other self."
Dr Jesse Selber, a plastic surgeon from the MD Anderson Cancer Centre at the University of Texas, who had previously performed the first skull-scalp transplant, said the surgery was "incredibly challenging and complex".
His team of five plastic surgeons removed skin, tissue and blood vessels from Mary Jane's abdomen and transplanted it to Marian's back, connecting eight different arteries and veins under a microscope during surgery.
The hole in Marian's back was 21.5in by 8.5in (55cm x 22 cm), making it one of the largest tissue transplantations on record.
By donating skin to her sister, Mary Jane - in effect - got a giant tummy tuck.
Having an identical twin made the transplantation process more likely to succeed for Marian because no suppression of her immune system was required - but there were still huge risks.
Surgeons said they were concerned about the donated skin being rejected and the possibility of the cancer recurring.
Although the tumour in Marian's back was very aggressive, it was not a type that spreads to other parts of the body so receiving her sister's skin and tissue was a perfect fix.
Dr Selber said: "Marian's wound was impossibly large - without her genetically identical sister, we would not have had enough tissue to reconstruct it."
The surgery took 14 hours and involved "extensive resection through skin, muscle and bone", followed by "hours of meticulous microvascular work".
This involved re-connecting countless veins and arteries.
The surgery was meticulously planned beforehand - and it paid off, according to Dr Selber.
"It went quite beautifully," he said.
Before the transplant surgery, Marian was in horrible pain. She couldn't lie on her back or sit up in a chair properly.
One month on from the surgery, the twins have been discharged, the stitches have been removed and they have returned home.
Marian says: "I'm looking forward to getting back to work, driving, running and sitting comfortably.
"I've never been sick before 2012 and am ready to get back to life."

Don and Maxine Simpson from Bakersfield, California, died four hours apart on adjoining beds, holding hands during some of their final hours.
Melissa Sloan said her grandmother died first and when her body was removed from the room, her husband followed.
"All Don wanted was to be with his beautiful wife. He adored my grandmother, loved her to the end of the earth," she told KERO-TV.
He was 90 and she was 87, and they met at a bowling alley in Bakersfield in 1952, getting married in the same year.
When civil engineer Don worked for the US Army, the couple spent some time in Germany, where they adopted twin 18-month-old boys from an orphanage.
They returned to Bakersfield, where she worked as a nurse and he owned his own engineering firm.
They are survived by one son and five grandchildren.

Question: Letting agency fees for tenants should be abolished in Wales as soon as possible, a Labour AM has said.

This is part of a news article. Represent it to retrieve the first (missing) sentence of the article

Chancellor Philip Hammond has announced the fees will be banned in England.
Jenny Rathbone, AM for Cardiff Central, said she was frustrated the "English government" seemed to have "stolen a march" on Wales.
Finance Secretary Mark Drakeford said the context in Wales was "completely different", and he wanted to see how a ban on fees in Scotland worked first.
Tenants can be charged fees for a range of administrative reasons, including for credit, reference and immigration checks.
In Scotland, lettings agency fees to tenants have already been banned.
Ms Rathbone said many of her constituents were private tenants "and are subject to really quite extortionate letting agency fees".
The backbench AM said agencies could charge fees for properties to be taken off the market, which she described as "money for nothing".
"I just feel a bit frustrated really that the English government seems to have stolen the march on us," she said.
Ms Rathbone said the Welsh Government should take action as soon as possible, "otherwise Wales is protecting tenants in this regard less than in England and Scotland".
If the government does not move on the issue, Ms Rathbone said she would apply to create a private member's bill in the assembly to do so.
Ms Rathbone had voted against a Plaid attempt to allow for a ban to be implemented last year, but she said she did this after being told by the Welsh Government it did not think the assembly had the power to ban the fees.
But she said she had since found out the "best legal advice" was that the assembly does hold that power.
John Puzey, director of housing charity Shelter Cymru, said people had been coming to its housing advice services saying they were having "great difficulty" getting the money together to enter into the private rented sector.
"Not only do they have to come up with rent in advance, deposits and all that sort of stuff, but they also had to pay quite often really steep charges," he said.
But Residential Landlords Association chairman Alan Ward, who has spoken out against the proposed ban in England, said: "Agent fees have to be paid by somebody.
"If any additional fees are passed on to landlords, tenants will end up paying them forever as market rents will increase."
Mr Drakeford told BBC Radio Wales the Welsh Government had already committed to exploring the evidence from Scotland, and would "look at the fine print" of the proposals for England.
He said some housing organisations had criticised the chancellor's plans, saying they would "simply feed through into higher bills for tenants in rent and will cost them more in the long run".
"If there is a good idea here, and using the experience elsewhere, then we will certainly study it," Mr Drakeford said.
"But the context is different in Wales. We have a different legal framework already. We have a different set of arrangements in place."
In Wales, a new regime requiring landlords to register came into force on Wednesday.
Plaid Cymru housing spokesperson Bethan Jenkins accused Welsh Labour of "hypocrisy and division" over the issue.
She said Labour AMs had voted against a Plaid amendment to the Renting Homes Act which would have scrapped the "punitive" fees.
"While the Labour Welsh Government contradict and undermine each other in public, we will continue to fight for a fair deal for renters in Wales," she said.
Welsh Conservative AM David Melding said: "Sadly, Wales now lags behind the rest of Britain when it comes to letting agent fees.
"It is time that the Welsh Government moved to protect tenants from additional costs."

Labour has vowed at a UK level to outlaw the contracts entirely.
Plaid Cymru accused Labour of voting against its own election pledge, but Labour said it has led the way in getting rid of zero-hours contracts.
The vote would not have meant a change to government policy, but would have indicated symbolic support.
Zero-hours contracts have been controversial - advocates say they offer employees flexibility, but opponents argue they constitute exploitation with employees not offered minimum hours.
The Welsh Government has previously proposed that the contracts are restricted in the social care sector, but Plaid Cymru on Wednesday called for the contracts to be "scrapped".
The call - part of a broader motion on local government - failed to pass in the assembly, receiving 12 votes for and 35 against.
Welsh ministers have also proposed to offer public sector staff reviews if they are on contracts without guaranteed hours but work regular shifts, and have pledged to limit their use within the Welsh Government.
Sian Gwenllian, Plaid Cymru's local government spokeswoman, told an assembly debate that if Labour supported the motion it would be "a clear sign that you are on the side of some of our most valuable but least respected workers in Wales".
Her party colleague Rhun ap Iorwerth said: "The Labour Party has reached a new level of incompetence in managing to vote against their own key election pledge just four days after launching it."
Plaid Cymru has said it is the seventh time there has been a vote on the issue in the chamber - and six times prior Labour and the Conservatives have voted against.
Mark Drakeford, Welsh Government Secretary for Local Government, said figures from the Institute for Fiscal Studies said social care spending by local authorities in Wales was 20% higher than it was in England.
A Welsh Labour government spokesman said: "Welsh Labour has led the way when it comes to getting rid of zero-hours contracts: we've done so in government and we've done so in organisations that are funded by government.
First minister Carwyn Jones on Tuesday said some of Plaid's attempts to ban the use of zero hours contracts in the past would have jeopardised the passage of legislation "because of the lack of clarity over devolved competence".
The law around employment is not devolved and is currently controlled by the UK government. Conservative AMs joined Labour in opposing the motion.
A spokesman for the Welsh Conservatives said: "While not suitable for everyone, we believe that zero-hour contracts do have a part to play in a modern, flexible labour market because, for a small proportion of the workforce, that may be the kind of contract that is right for them."
However he added it was important that those contracted under such terms are not exploited. "Action has been taken to this end," he said.
UKIP AMs voted with Plaid Cymru on Wednesday.
A UKIP Wales spokesman said: "Our party has been raising concerns about zero hours contracts for a long time.
"Zero-hours contracts take us back to the 19th century, when workers were forced to turn up at dockyard gates to be given, or not given, a single day's work. They have no place in 21st century Britain."
The Liberal Democrats raised question marks over Plaid Cymru's record on the issue in local government, suggesting it said one thing in the assembly and did another elsewhere.

After failing to qualify for a second straight Nations Cup the fans and players of the 2013 champions will have to watch from the sidelines again.
The 27-year-old says the reality of their failure will really hit home when the tournament kicks off on 14 January.
"I felt bad - not just me but Nigerians as a whole are not happy," he admitted
"Seeing teams playing in the Nations Cup and you see yourself at home you know you're not going to the Nations Cup that's when i am going to feel bad."
"You know you don't have to dwell on that, we don't have to kill ourselves about that.
"We have to work towards the next one and keep pushing hopefully we will qualify."
Before they can think about reaching the next Nations Cup in Cameroon the Super Eagles have the 2018 World Cup qualifiers to negotiate.
Nigeria are currently top of their World Cup group with two wins out of two and continue their campaign at home to Cameroon in August.

Sixty years have passed since the first Nations Cup, which took place in Sudan in 1957, consisted of only three teams and was won by Egypt.
This year's edition has 32 matches over 23 days, featuring 16 teams - who begin their quest in four groups of four - and will end on 5 February with the winning finalists lifting the Italian-made trophy and taking home $4m (£3.28m).
Africa remains enthralled by the tournament, which has steadily grown to become the continent's biggest sporting event, and the 2017 finals are guaranteed to provide a mix of flair, surprise, controversy and historic moments.
Gabon welcomes back the cream of African football only five years after it co-hosted the Nations Cup with Equatorial Guinea.
The country was awarded the finals by the Confederation of African Football as replacement for Libya, which had been due to host in 2013 but swapped years with South Africa which had been selected to host in 2017.
The civil war in Libya meant it had to withdraw entirely and in stepped Gabon.
However, the oil-rich country with a population of 1.8m has been experiencing its own troubles since incumbent President Ali Bongo was declared the winner of a contested election in August. His victory was followed by deadly clashes on the streets.
Opposition activists have called on citizens to boycott the tournament as part of their plans to highlight their protests against Bongo's rule.
On the pitch, Gabon are the lowest ranked team in the finals, occupying 108th spot in Fifa's world rankings for January.
But they do have in their side one of the world's most coveted strikers in Pierre-Emerick Aubamenyang. The Borussia Dortmund forward goes into the tournament in scintillating form, having scored 20 goals in 22 games this season for his German club.
As well as Aubameyang, many eyes will be on reigning BBC African Footballer of the Year and Caf African Footballer of the year Riyad Mahrez and Africa's most expensive player Sadio Mane.
Leicester winger Mahrez will be a key figure in an Algeria team which until recently had been ranked the best team in Africa.
Mane, who cost Liverpool £34m, leads the line for Senegal. The Teranga Lions have never won the event but Mane could be the key to changing that statistic.
Twenty three players from English Premier League clubs will be in Gabon including Mahrez, Mane, Manchester United's Ivorian defender Eric Bailly, West Ham's Ghanaian Andre Ayew, Leicester's Algerian Islam Slimani and Crystal Palace's Ivorian Wilfried Zaha.
Winger Zaha has only just switched international allegiance from England and started his career with the Elephants in sensational style by scoring on his second appearance for the team in a friendly against Uganda earlier this week.
Egypt's Mohamed Salah has been outstanding since his switch from Chelsea to Italian giants Roma. Once labelled the African Messi, the winger has recently recovered from injury but if he can find his best form he could light up the tournament.
At the other end of the spectrum, Guinea-Bissau skipper Bocundji Ca was playing for third division French club Paris FC last season.
Togo coach Claude LeRoy is making a record-extending ninth appearance at the finals and leading a sixth different nation. The Frenchman, considered the Godfather of the Nations Cup, has won the tournament once - with Cameroon in 1988 - and has only once failed to reach the quarter-finals stage.
Egypt goalkeeper Essam El Hadary can become the oldest player in the tournament's history - if he gets some game time in Gabon. The veteran shot stopper turns 44 on 15 January. Compatriot Hossam Hassan holds the record - he was 39 when he played in 2006.
The Pharaohs have won the tournament a record seven times and they have a chance to further pull away from the pack for the first time since their last success in 2010. Failure to qualify for the last three editions has marred their recent past and they will relish the chance to re-establish themselves at the top table.
Herve Renard is aiming to become the first coach to win the title with three different teams. The Frenchman lifted the trophy with Zambia in 2012 and led Ivory Coast to glory last time out.
He is aiming to make it a hat-trick with Morocco. Only two coaches have won the Cup of Nations three times - Charles Gyamfi achieved the feat in charge of Ghana in 1963, 1965 and 1982 and Hassan Shehata also won it three times with Egypt between 2006 and 2010.
Guinea-Bissau are making their first appearance at the finals. Their qualification is virtually the stuff of fairytales: one of the world's poorest countries overcoming 2012 champions to top their group, having previously won only four of 32 matches in their history.
With a squad almost entirely made of expatriates who are based in the lower leagues of Portugal, few expect Guinea-Bissau's run to continue but what a story it is already.
It is the first time in 39 years that Uganda are at the tournament. And in a curious twist of fate they are paired in a group with Ghana, who were hosts in 1978 - the last time Uganda qualified - and beat the Cranes 2-0 in the final.
Uganda were named National Team of the Year at the recent Caf awards and goalkeeper Denis Onyango was named Africa-based Player of the Year. They are a team on the rise but it would be a major shock if they went deep into the tournament.
"When I view the Algeria, Ghana, Ivory Coast and Senegal squads, I realise we are not among the best on paper, but there will be 23 highly committed Togolese footballers at the Cup of Nations." Togo captain and striker Emmanuel Adebayor, who has been without a club since his release by Crystal Palace in June 2016.
"We are victims of blackmail." - Cameroon official Simon Lyonga is unhappy with European club managers who he believes privately encourage their players to reject call-ups to play in the Nations Cup. Eight Cameroonians, including Liverpool defender Joel Matip, opted out.
"With these kind of decisions they are controlling every second so, for sure, they are going to win the African Cup." - Manchester United manager Jose Mourinho vented his anger at Ivory Coast's refusal to delay the departure of centre-back Eric Bailly by 24 hours so he could play against West Ham.
"The fact that I have had a lot of success in recent years also makes people think that alone can make the difference. But that doesn't matter, what matters is the spirit of the team and the way we go into our matches." - Morocco coach Herve Renard plays down his own influence on proceedings.
"There aren't many differences between coaching in Europe and Africa except that one day you might be having lunch with the head of state and then the next day you are standing alongside some dusty field looking at a prospective player."- Togo coach Claude LeRoy on the particular demands of managing on the continent.
"Avram Grant has taken us as his children, always checking on us, how conditioned we are. Even if you aren't part of the team he motivates you to train harder and get much playing time in your team." - Ghana's Afriyie Acquah is full of praise for the former Chelsea manager Avram Grant, who is widely expected to lose his job after the tournament no matter whether he leads the Black Stars to a first title in 35 years or not.
Reigning champions Ivory Coast have a new-look squad following the international retirements of legendary players such as Yaya Toure and Didier Drogba. They struggled in qualifying but the same was true before they won the trophy two years ago. New recruit Zaha is tipped to be used as the main striker for the Elephants - it will be intriguing to see how that works out.
Ghana might be considered the Germany of Africa - they always seem to come good at tournaments. But the last of their four titles came in 1982 and they have suffered defeat in the final three times since then, including on penalties to Ivory Coast last time out. Can they go one better in Gabon?
Algeria boast Africa's hottest property in 2016, Mahrez, and his Leicester team-mate Slimani as well as Porto midfielder Yacine Brahimi. They were unbeaten in qualifying and have strength in depth in their squad. They will be confident in their chances of winning a second title.
Senegal qualified with a 100% record and if they can maintain that kind of form, and Mane clicks up front, they will surely have a good chance of being there at the finals stages of the tournament. Alongside Mane, they have big talent in the likes of Napoli defender Kalidou Koulibaly, West Ham midfielder Cheikhou Kouyate and Fenerbahce striker Moussa Sow.
Egypt also enjoyed a strong qualifying campaign and have the pedigree to perform when it matters most. Like Senegal, they will look to one player more than any other - Salah is charged with providing the inspiration to win matches.
However, it is notoriously difficult to predict Nations Cup winners - Zambia caused a huge upset to take the title in 2012, giants Nigeria are once again absent, Ghana's fifth title is proving elusive and the competition is getting tougher all the time.
As Ghana's Andre Ayew says: "I think the Cup of Nations is becoming increasingly difficult to win because all the teams are getting stronger."

Question: People in serious debt can expect more legal protection from bailiffs, charges and interest after pledges in the major parties' manifestos.

Represent the news article to find a single sentence that could be used as a summary

The Conservatives and Labour have vowed to extend a "breathing space" scheme used in Scotland to allow people time to organise repayments.
Others, including the Lib Dems, want more regulation in the debt sector.
There is widespread concern over the levels of personal debt among working households.
The City regulator - the Financial Conduct Authority (FCA) - has warned of an acceleration in consumer borrowing, such as loans, overdrafts, credit card debt and car finance. This echoes concerns raised by the Bank of England.
The total amount of consumer debt tops £1.5 trillion. Although this is dominated by mortgage borrowing, there is a vast array of debt products creating concern.
A Lords committee also recently called for stronger controls such as a cap on "rent to own" products.
The FCA is already conducting is own inquiry into overdrafts, door-to-door lending and other forms of loans. Consumer groups have consistently argued there should be an overdraft cap in place.
The regulator estimates that 3.3 million people are in persistent credit card debt.
The biggest focus in recent times has been on car finance deals. The value of finance deals used to buy new cars has soared to a new monthly record, according to latest figures, with motorists having spent £3.6bn on deals in March.
The fear is that households, with a regular but stagnant salary, are using their income to fund an increasing amount of debt, leaving them at risk if interest rates were to rise from historic lows.
Mike O'Connor, chief executive of debt charity StepChange, said: "In addition to better protections for people in debt, the next government should commit to action to prevent the 8.8 million people currently showing signs of financial difficulty from falling into serious hardship.
"It should work to ensure better alternatives to dangerous forms of high-cost credit, and it should act to help families build up savings to insulate them from problem debt."
More than 16 million people in the UK have savings of less than £100, according to the Money Advice Service, leaving them further exposed to a financial shock.
In five areas - Northern Ireland, the West Midlands, Yorkshire and Humber, North East England and Wales - more than half the adult population has savings below £100.
There is a risk to UK economic stability too, with lenders standing to lose much more on their consumer credit loans than they would on mortgage lending if there is an economic downturn and their borrowers default on their credit card and other personal loans.
Proposed action includes:
StepChange welcomed the breathing space scheme for those in serious debt - but said this should be extended to a year.
It said this would allow those in debt owing to issues such as family breakdown or a reduction in working hours to be allowed time to rebuild their income to prepare to repay what they borrowed.
Campaigners have also called for greater protection for those facing mental health difficulties, particularly regarding store cards and "impulse" borrowing.
Polly Mackenzie, director of the Money and Mental Health Policy Institute, said: "Customers are encouraged to take out complex new credit deals on the spur of the moment, at the front of a queue in a shop or in a few clicks at an online checkout.
"For people with mental health problems in particular this is leading to real financial difficulty, encouraging impulsive spending that can be a symptom of a number of mental health problems, and setting people up in credit arrangements that they often don't fully understand."

PM David Cameron made the announcement as the Conservatives gathered in Manchester for their annual conference.
He rejected fears the Help to Buy scheme will fuel a housing bubble.
He told the BBC's Andrew Marr show the market was "recovering from a very low base" and first-time buyers needed help to get on the housing ladder.
"As prime minister I am not going to stand by while people's aspirations to get on the housing ladder are being trashed."
He added: "If we don't do this it will only be people with rich parents to help them who can get on the housing ladder - that is not fair, it is not right."
He rejected concerns - raised by Business Secretary Vince Cable among others - of an unsustainable boom in house prices, particularly in the south-east of England.
The prime minister urged people to "trust" the Bank of England, which has been given an enhanced role in monitoring the effect of the scheme on prices.
And he said mortgage-lenders, including the Halifax, RBS and Nat West, had already signed up to it.
Some of the UK's biggest lenders - HSBC, Santander, Nationwide and Barclays - have yet to decide whether to take part, the banks told the BBC.
Mr Cameron also used his Andrew Marr interview to stress that there would be no "mansion tax" if he his prime minister after the next election, making it clear that this would be a so-called "red line" - a point he would refuse to concede - in coalition negotiations.
A property tax on more valuable homes - known as a mansion tax - is a key demand of the Liberal Democrats.
Meanwhile, about 50,000 people took part in a union protest outside the conference against government austerity policies, particularly those affecting the NHS.
Greater Manchester Police described it as one of the largest protests they had ever policed.
In other developments:
Mr Cameron admitted to mistakes in the way the government handled the gay marriage issue, saying:  "I don't think I expected quite the furore that there was."
He said he understood and respected people's difficulties with the policy and said the government had failed to convey the fact the policy would not affect what happened in churches, mosques and synagogues.
The Conservatives will use their week in Manchester to unveil a series of policies aimed at showing they are "on the side of hard working people". Other policy announcements are set to include a crackdown on welfare payments and an expansion of free schools.
Labour extended its lead in the opinion polls after announcing at its conference last week that it would freeze energy prices and increase corporation tax to pay for a cut in business rates for small firms.
Mr Cameron dismissed Labour leader Ed Miliband's economic strategy as "nuts," arguing that increasing tax on big business risked choking off the recovery.
He said the only way to "sustainably raise living standards is to keep the recovery going, and the economy is now moving, to keep on creating jobs...to keep on cutting the deficit."
Under the first phase of the Help to Buy scheme, launched in April, the government will give homebuyers in England equity loans of up to 20% of the price of a new property worth up to £600,000.
Homebuyers need to contribute at least 5% of the property price as a deposit, with a 75% mortgage to cover the rest.
Under the second phase of Help to Buy, which had been due to launch in January, the government will underwrite 15% of the value of a mortgage, allowing people to buy properties with a 5% deposit.
It will apply to all home purchases in the UK of up to £600,000.
Applications for loans from the scheme will now be brought forward to the week beginning 7 October but the loans will not be paid out until 1 January. Anyone hoping to complete on their home purchase using the second phase of Help to Buy before 2014 will not be able to.
Adam Marshall, of the British Chambers of Commerce, said: "With all the concern expressed about Help to Buy - rushing into it seems less than responsible on part of government."
House prices rose at their fastest rate in more than six years in September, according to property analysts Hometrack.
Labour said the government needed to build more houses to ease shortages.
"Unless David Cameron acts now to build more affordable homes, as Labour has urged, then soaring prices risk making it even harder for first time buyers to get on the housing ladder," said Shadow Chancellor Ed Balls.
"You can't deal with the cost of living crisis without building more homes, so it's no wonder that for millions of families this is no recovery at all.
It comes as a poll of more than 1,400 Conservative councillors in England and Wales for BBC One's Sunday Politics suggested nearly a quarter would support an electoral pact with the UK Independence Party (UKIP) at the next general election.
A Tory source said: "80% of our councillors didn't respond to this survey so it's hardly representative. It should be taken with a large pinch of salt."
The conference opened on Sunday with a tribute to former Prime Minster Baroness Thatcher, who died aged 87 in April.
It will close with Mr Cameron's keynote speech on Wednesday.

Question: Musician Frankie Knuckles, known as the Godfather of House music, has died unexpectedly, it has been announced.

A pioneer of house - the sparse, electronic dance music that emerged from Chicago in the 1980s - Knuckles was just 59.
He was known for remixing tracks by Michael Jackson and Whitney Houston, as well as his own songs, such as Your Love and The Whistle Song.
His death was confirmed by fellow DJ David Morales on Twitter.
"I am devastated to write that my dear friend Frankie Knuckles has passed away today," he wrote. "Can't write anymore than this at the moment. I'm sorry."
Knuckles' longtime business partner, Frederick Dunson, told The Chicago Tribune he had "died unexpectedly this afternoon at home".
That was confirmed by the Cook County medical examiner who said Knuckles died on Monday in Chicago. The medical examiner said a cause of death was not available.
Several music websites have reported Knuckles had died of complications from Type 2 diabetes.
In the mid 2000's, the DJ had developed the bone infection osteomyelitis after breaking bones in his foot while snowboarding. In 2008, he had the foot amputated after refusing to let up on his punishing work schedule.
'Art form'
Born in the Bronx, Frankie Warren Knuckles Jr learned his craft in New York City, where he was mentored by club DJ Larry Levan.
"We would spend entire afternoons working up ideas on how to present a record so that people would hear it in a new way and fall in love with it," Knuckles later recalled. "To us it was an art form."
He moved to Chicago in the 1970s, just as disco was dying out, and pioneered a style of extending soul and R&B records by adding drum machine loops.
"I would program different break beats and use them as segues between songs and additional beats," he said in 2011. "I had my own little piece of heaven right there."
He made his name at The Warehouse, a club in northern Chicago, predominantly patronised by gay men from the black and Latin-American communities.
"The people that used to hang out at The Warehouse coined the phrase 'House Music'," Knuckles said.
"At the time I was the only DJ in the city playing a sound that they heard nowhere else.
"So, when dance parties and regional DJs began popping up on the South Side of the city, to attract the same kind of audience that I had at The Warehouse.... they would advertise that they played 'House Music'."
By 1982, Knuckles had opened the his own venue for house music, called the Power Plant, where he premiered several tracks by local artist Jamie Principle, recorded on reel-to-reel tape.
The DJ helped secure a commercial release for several of those tracks - including Your Love and Baby Wants to Ride - which are recognised as the some of the earliest house classics.
Your Love is possibly better known in the UK as the backing track for The Source's hit remix of Candi Staton's You Got The Love.
Knuckles also produced the house anthem Tears with Robert Owens, and began his remixing career with a version of First Choice's Let No Man Put Asunder.
He later signed to Virgin Records, where he remixed or produced such artists as Mary J Blige, Janet Jackson, Pet Shop Boys, Diana Ross, Luther Vandross and Toni Braxton, and won a Grammy for best remixer of the year in 1997.
Inducted to the Dance Music Hall of Fame in 2005, Knuckles also had a Chicago street named after him in 2004, on the former site of the Warehouse club.
BBC Radio 1's Pete Tong was among those paying tribute to the star on Twitter, writing: "RIP gentleman genius, groundbreaker, inspiration. Blessed to have worked with you."
"I can't begin to count the ways he influenced me but I will never forget," added house DJ Roger Sanchez.
"Frankie Knuckles was so under-appreciated," added Questlove, leader of hip-hop group The Roots. "He was the DJ that DJs aspired to be."
The star had been as busy as ever in the run-up to his death, playing London's Ministry of Sound on Saturday night.
His Facebook page listed several upcoming dates over the next few months.

The musician scored his biggest hit in 1985 with the club single Trapped, which reached number three in the UK.
Last year, it emerged he was living homeless in New York. Friends then launched a fundraising campaign to help him obtain vital diabetes medication.
His death was announced on Facebook by DJ Tony "Tune" Herbert, who said: "Now he is at peace."
He added: "Our condolences go out to his family and fans world wide. He is no longer suffering or Trapped."
Colonel Abrams - his real name - was born in Detroit, the home of Motown, in 1949.
He said his music was a blend of those melodies and the hard street rhythms of New York, where he moved as a child.
"I studied all the people on Motown, and I studied the music and listened to the lyrics Smokey Robinson used to write, and just craved the opportunity to be on Motown," he told the Associated Press news agency in the 1980s.
"But after my family moved to New York, I studied street music, and I sort of combined them both: The Detroit sound and the street sounds of New York."
Abrams was in the group Conservative Manor with his brother Morris in the late 1960s, then sang lead vocals for 94 East in 1976.
They briefly featured Prince on guitar, and recorded his song Just Another Sucker in 1977.
The band dissolved once Prince's solo career took off, and Abrams joined Surprise Package, a New Jersey group.
He scored a small hit in 1984 with the ballad Leave the Message Behind the Door but it was the follow-up, a soulful house mantra called Music Is The Answer, which finally propelled him into the limelight.
An international dance hit, it earned him a record deal with MCA - which led to the chart hits Trapped and I'm Not Going to Let You.
Abrams continued to feature on the US dance and R&B charts into the mid-1990s, and performed around the world into the new century.
However, he fell upon hard times in his final years, prompting Herbert and house DJ Marshall Jefferson to launch a crowdfunding campaign.
"The Colonel is very ill with no permanent place of his own to live at this time and limited financial resources," they said at the time.
"Those of us who have listened to his awesome music and know of his plight, have banded together to try and help him through this rough patch."
According to Herbert, the musician died on Thanksgiving.
Joey Negro, Dave Pearce and Swizz Beatz are among those to have paid tribute online.
"It's a sad day for the House Music community," wrote Jellybean Benitez, a producer who worked on Madonna's Holiday and Whitney Houston's Love Will Save The Day.
"Just learned Colonel Abrams passed away," added Jefferson. "Never to be forgotten, R.I.P."

Question: Nigel Farage has resigned as leader of UKIP having failed to gain the seat of Thanet South, losing out to Conservative candidate Craig Mackinlay.

But he said he would consider running for the job again when the leadership contest is held in September.
Speaking about his defeat, he insisted he had "never felt happier", with a "weight lifted off his shoulders".
UKIP has won a 13% vote share in the election and has one MP, Douglas Carswell, who held his Clacton seat.
It puts the party in third place behind the Conservatives and Labour in terms of share of the vote.
Mr Farage said the results proved there needed to be a change to the voting system.
"Personally, I think the first-past-the-post system is bankrupt," he said.
"It is bankrupt because one party can get 50% of the vote in Scotland and nearly 100% of the seats, and our party can get 4 million votes and just one seat."
He added: "For those reasons there are a lot of angry UKIP people out there. They're not giving up on UKIP, but absolutely determined that we get a fairer, more reflective system."
On the eve of polling day, UKIP leader Nigel Farage told interviewers he would be "for the chop" if he failed to get elected in the Kent seat of South Thanet.
And so it proved, when he lost out to Conservative Craig Mackinlay by almost 3,000 votes.
While the self-styled leader of the purple "People's Army" will mourn the death of his dream, Mr Farage will doubtless take consolation in the party's transformation under his stewardship.
In full: The Nigel Farage story
Mr Farage claimed there was a new type of UKIP voter - predominantly working class, very much younger than before, and in particular young women now voting for the party.
He said he would keep his promise of standing down as leader following his defeat, but said he would not rule out the job in the future.
"There will be a leadership election for the next leader of UKIP in September and I will consider over the course of this summer whether to put my name forward to do that job again," he said.
He also said he would recommend Suzanne Evans, the deputy chairman, to be stand-in leader until the leadership challenge is complete.
UKIP failed to win the key target seats of Castle Point, in Essex, as well as Labour-held Great Grimsby. It also came third in Thurrock - another high priority seat.
Mark Reckless also lost out to Tory candidate Kelly Tolhurst in Rochester and Strood by 16,009 votes to 23,142.
He had represented the Kent constituency for the Conservatives from 2010 until switching allegiance to UKIP and beating Ms Tolhurst at last November's by-election.
Mr Reckless told reporters: "I always knew what I was doing was a risk but nobody should underestimate UKIP's achievement."

Rochester and Strood was won by Conservative candidate Kelly Tolhurst with a majority of more than 7,000.
In November, Mr Reckless fought a by-election in the constituency, beating Ms Tolhurst.
Mr Farage has resigned as party leader following his defeat in South Thanet.
The Conservative candidate Craig Mackinlay took the South Thanet seat with a majority of 2,812.
He said: "I'm delighted. I've given promises on Manston Airport and we're working, leaving no stone unturned, to make sure it opens.
"I've got a fairly unique plan for the regeneration of Ramsgate."
Mr Mackinlay, a former UKIP leader and Medway councillor, takes over the seat from Laura Sandys, who stood down as Conservative MP at the election.
Mr Reckless, who held the seat at a by-election after defecting from the Conservatives to UKIP, said: "I always knew what I was doing was a risk but nobody should underestimate UKIP's achievement.
"I am proud to have been a part of that and to have represented the people of Rochester and Strood for the past five years."
The BBC's political correspondent, Ellie Price tweeted; "Mark Reckless tells new Rochester & Strood MP Kelly Tolhurst: 'Never ever forget who your bosses are.'"
Labour came third with just over 10,000 votes, while the Lib Dems came fifth to the Green Party with 1,251 votes.
The Conservatives have held Chatham and Aylesford, with Tracey Crouch retaining her seat, with a share of just over 50% of the votes.
Conservative Roger Gale has kept his Thanet North seat with a majority of almost 11,000 over the UKIP candidate Piers Wauchope.
Rehman Chishti has retained his seat in Gillingham and Rainham for the Conservatives, with a majority of more than 10,000 votes.

Question: An MSP has written to Perth and Kinross Council urging a "major review" of T in the Park's move to Strathallan Castle.

Festival bosses apologised after a number of revellers were caught up in transport problems and delays following the event's first year at the site.
In a letter to the chief executive, Conservative MSP Liz Smith claimed "public safety was compromised".
Councillors gave permission for the annual event to be held at Strathallan for three years.
DF Concerts issued apologies for transport issues on each day of the festival, with long queues forming at pick-up and drop-off points. Police made 54 arrests, and a 36-year-old man was found dead in the toilets.
Festival director Geoff Ellis said his team would "take learnings" from the issues for subsequent years, and noted that previous events at Balado had benefitted from years of infrastructure and practice.
The festival was only given permission to move to Strathallan after a lengthy planning dispute, which included concerns from local residents about the suitability of the local road network.
Permission was given for three years, during which time councillors said the impact of the event would be monitored, to inform decisions on its long-term future.
In her letter to Bernadette Malone, Ms Smith said revellers and local residents had suffered "misery", and said there was "an urgent need to undertake a full, balanced and transparent review of the whole event and the planning process".
She said it was "abundantly clear that public safety was compromised", due to issues with pedestrian safety on nearby roads, serious traffic congestion, "the lack of adequate policing and stewarding" and poor hygiene in the toilet areas.
She said: "The volume and extent of the complaints is significant. This includes evidence provided by many loyal and long-serving T in the Parkers who said that this year was the worst experience they had endured."
"I remain very concerned that the advice of local people and those who know the area best was, on occasion, disregarded.
"It is not enough to say the problems encountered were 'teething troubles'. The extent of the complaints both by attendees and local people makes a mockery of that description."
Event officials said a number of factors had contributed to the traffic problems, including poor weather creating "challenging ground conditions".
Manger Colin Rodger said approximately 500 people had attempted to walk three miles back to an unofficial campsite "in an unsuitable location", restricting access to pick-up points, despite festival bosses underlining that there was no pedestrian access to the site.
Mr Ellis admitted the event had "not been perfect", but said he had "never expected it to be".
He said: "Obviously with any festival that moves site, particularly one on the scale of T in the Park, you're not going to get everything right in the first year. We fully accept that.
"We know traffic queues have left some people frustrated and we apologise for this, because obviously we want the experience to be positive for everyone from start to finish.
"We'll take learnings from this year and will work on improving the times for the future.
"Overall it's been a great first year at Strathallan - the bands were brilliant, the site looked wonderful and we know that the majority of people have had a fantastic time."
Ch Supt Eddie Smith of Police Scotland said: "DF concerts has already acknowledged that there were issues with the event and has apologised for that.
"Police Scotland totally refutes that there were inadequate policing resources for the event. I will be seeking a meeting with Liz Smith to discuss what her concerns are."

Geoff Ellis, of DF Concerts, told the BBC Strathallan was the "right venue".
But he added that he did not think the festival could continue if it did not go ahead at the site this year.
There has been vocal opposition to the site on environmental grounds, compounded by the recent arrival of ospreys, which are protected.
With just three months to go, Perth and Kinross Council has yet to make a final decision on whether to allow the festival.
Earlier this week, it was revealed that ospreys had returned to nest at the proposed site, with festival organisers and RSPB Scotland pledging to work together to safeguard the birds.
Ospreys are a protected species and cannot be disturbed while nesting. Police were called to the site on Monday and are monitoring the situation.
However, some local people and nature organisations such as the Woodland Trust have objected to the site more widely, citing risks to the local ecosystem.
Mr Elllis was asked on BBC Radio's Good Morning Scotland programme whether the festival would continue if it did not take place at Strathallan.
He said: "I don't think there is a venue, without going very far north in Scotland, which would be viable for T in the Park, so yes, I don't think it would carry on if we didn't host it at Strathallan this year."
Mr Ellis added that "Scotland needs T in the Park", pointing out that it generated more than Â£15m for the economy last year.
However, on the same programme, Charles Dundas, of the Woodland Trust Scotland, said "irreplaceable" ancient woodland could be lost if the festival goes ahead at Strathallan, adding that festival organisers had not done enough to satisfy them that nature would be protected.
Tickets have already been sold for the festival, planned for 10-12 July and set to feature bands including The Libertines, Kasabian and Noel Gallagher's High Flying Birds.
T in the Park was held at Balado, near Kinross, from 1997 until last year, when it was forced to move after "substantial" concerns were raised by health and safety inspectors about an oil pipeline which runs underneath the site.
Up to 85,000 revellers have attended each day of the festival in recent years.

Question: Turkish police have arrested the main suspect in the New Year's Eve attack on an exclusive nightclub in Istanbul after a huge manhunt.

Abdulkadir Masharipov is believed to have mounted the assault on the Reina club which left 39 people dead.
The Uzbek national is said to have been caught in Istanbul's Esenyurt district.
Citizens of Israel, France, Tunisia, Lebanon, India, Belgium, Jordan and Saudi Arabia were among the victims, and dozens of people were injured.
So-called Islamic State (IS) said it was behind the attack, saying it was revenge for Turkish military involvement in Syria.
The gunman arrived at the club by taxi early that Sunday, before rushing through the entrance with a long-barrelled gun he had taken from the boot of the car.
He fired randomly at people celebrating the new year.
It was the culmination of a huge police manhunt: a raid on the Istanbul suburb of Esenyurt that finally caught the alleged Reina attacker, named as Uzbek national Abdulkadir Masharipov.
Photographs show him with a heavily bruised face, wearing a grey T-shirt and being held by his throat.
There had been fears that the gunman had managed to escape Turkey, perhaps to territory held by so-called Islamic State, which said it was behind the attack.
The Turkish authorities will be hugely relieved at his capture. But the far greater challenge for them is to secure this country and step up intelligence to halt the wave of terror attacks that has engulfed Turkey.
Police reportedly found the suspect along with his four year-old son at the home of a Kyrgyz friend in the city. Turkish media say that his friend was also detained, along with three women.
According to the Hurriyet newspaper, he was due to undergo medical checks before being taken in for interrogation at a police headquarters.
Sources: Turkish media
Turkish media report that the suspect rented a flat in the central Turkish city of Konya with a woman believed to be his wife and two children. He arrived in Istanbul on 15 December, according to Hurriyet's sources.
The reports add that police also carried out raids on other suspected IS militants.
Turkey has been battling IS inside northern Syria while seeking to push back ethnic Kurds in the region too.
Reina was one of Istanbul's best-known clubs, with a view across the Bosphorus towards Asia.
It attracted singers, actors and sports stars as well as foreign tourists.

One is said to be from Russia's North Caucasus region and the others from Uzbekistan and Kyrgyzstan.
Turkey believes so-called Islamic State (IS) was behind the suicide gun and bomb attack that left 44 people dead and some 240 injured.
Police detained at least 13 suspects in Istanbul and more in Izmir on Thursday.
Family, friends and colleagues of victims gathered at the airport on Thursday for a memorial service as funerals continued.
One image on Turkish media purported to show the three men together at the airport moments before the attack, wearing dark jackets and carrying holdalls. Two are wearing caps, one is smiling.
An unnamed Turkish official confirmed for Reuters news agency the dead attackers' countries of origin after Turkish media reports.
Some agencies named one of the men as Osman Vadinov, said to have crossed into Turkey from the IS stronghold of Raqqa in Syria in 2015.
Reports that he was a Chechen have been denied by an unnamed police source in the North Caucasus, Russia's Interfax news agency reports.
The organiser of the attack has been named by Turkish media as Akhmed Chatayev, a Chechen believed to have acted as an IS recruiter, who is on a US counter-terror sanctions list. His fate was not immediately clear.
IS has long recruited members from mainly Muslim parts of the former USSR, with Russian President Vladimir Putin putting the overall number at between 5,000 and 7,000 in October.
However, data published by the Soufan Group security consultants in December suggests the numbers are lower: 2,400 from Russia and 500 apiece from Uzbekistan and Kyrgyzstan.
Many believe that some elements within Turkey's Islamist-leaning government stomached, or even fostered, jihadist groups in Syria that tallied with their beliefs, creating an environment in which IS could grow.
For the first few years of the Syrian war, Turkey's border with Syria was somewhat porous, allowing jihadists and weapons to cross in both directions - until pressure from the US and others grew and Turkey tightened controls.
Ankara has always vehemently denied the allegations, claiming there is no proof of sinister cross-border movement and that the media and Western governments are attempting to besmirch Turkey while ignoring the fact that it has taken in almost three million Syrian refugees.
But what is clear is that as Turkey has become a more active part of the US-led coalition against Islamic State, it is considerably more vulnerable.

Islamic State: the full story
The government has made no official statement on nationalities yet and no-one has said they carried out the attack on Tuesday evening.
Turkish Prime Minister Binali Yildirim said on Wednesday that "our thoughts on those responsible for the attack lean towards Islamic State".
Meanwhile, another Turkish official told AFP news agency: "Earlier today, the police raided 16 locations to detain 13 IS suspects, including three foreign nationals."
Turkish media said counter-terrorism police had raided several areas of Istanbul - including Pendik, Basaksehir and Sultanbeyli.
Arrests were also reported in the western coastal city of Izmir, where at least nine people were detained, accused of financing, recruiting and providing logistical support to IS.
Separately, Turkish media reported that security forces had killed two suspected IS militants on the Syrian border last Saturday. They said one had been planning an attack on the capital Ankara or the city of Adana.
Detailing the attack, Mr Yildirim said the three men had wanted to pass through the security system but on seeing the controls "took their weapons out of their suitcases and opened fire at random at the security check".
One attacker detonated his explosives downstairs in the arrivals terminal, Turkish officials said.
The second went upstairs and set off his explosives there while the third waited outside as passengers fled. He then detonated his explosives, causing the most casualties.
A Kalashnikov assault rifle, a handgun and two grenades were found on the bodies, Turkish media said.
Some 240 people were injured, dozens of whom remain in critical condition in hospital.
Dozens of anxious friends and relatives remain camped outside Istanbul's Bakirkoy hospital, waiting for news.
It is now known that of the 44 people killed, 24 were Turkish, three were Saudis and two Iraqis. In addition, China, Jordan, Tunisia, Uzbekistan, Iran and Ukraine each lost one citizen, and two Palestinians were killed.
Funerals began on Wednesday, including that of Muhammed Eymen Demirci, who landed a job on the ground services crew in May after a year unemployed, texting a friend saying "I got the job bro!"
He died waiting for a bus.
Tunisian doctor Fathi Bayoudh had reportedly been in Turkey for some weeks trying to secure the release of his son, who had been detained for allegedly joining IS.
Marvan Melhim and his wife, Nisreen, both work in Saudi Arabia, and had arrived with their three-year-old daughter.
"We heard shooting from a distance," said Marvan. "The explosion went off. I found my wife bleeding and my daughter too." Nisreen died in hospital shortly afterwards.
A friend of Serkan Turk said the physical education teacher had rushed to the site of the first explosion to help the wounded, but was killed by a later blast.

Question: At least three people have been killed and nine injured in a train crash in the Belgian town of Hermalle-sous-Huy, near Liege, reports say.

A passenger train crashed into the back of a goods train at high speed at about 23:00 (21:00 GMT), said Belgium's rail infrastructure manager, Infrabel.
The two trains were on the same track, a spokesman for Infrabel said.
A local mayor said the passenger train was in a terrible state and it was fortunate there were no more victims.
Francis Dejon, major of Saint-Georges-Sur-Meuse province, said the front carriage of the passenger train had completely folded back on itself.
The train, with about 40 people on board, was travelling between Liege and Namur at about 90km/h (55mph) when it hit the goods train.
"Two of the six carriages derailed and are lying on the tracks," said a statement issued by Infrabel and national rail operator NMBS/SNCB.
Some of those injured had to be freed from the wreckage and are in critical condition, officials say.
Prime Minister Charles Michel tweeted his condolences to the families of the victims and wished the injured a speedy recovery.
Infrabel has begun an investigation into the crash.
There has been no comment as to why the trains were on the same track.
Infrabel said there had been what it called a "lightning incident" on the track earlier on Sunday and a tweet by SNCB had mentioned a signalling fault on the line at 21:30 local time on Sunday, although it said this had been cleared and services were normal.
"The investigation into the cause of the rail crash is fully under way. The lightning strike is a possible line of inquiry, but there are still safety systems which are supposed to come into place," spokesman Frederic Petit told public broadcaster VRT.
In February 2010, 18 people were killed when two passenger trains collided at Halle, south-west of the capital, Brussels.
Two people died and 14 were hurt in May 2013 when a train carrying toxic, flammable chemicals derailed and caused a major fire near the city of Ghent.

Question: Burkina Faso coach Gernot Rohr has not given up hope of having Jonathan Pitroipa available for their 2017 Africa Cup of Nations qualifier in Botswana next month.

Pitroipa, the player of the tournament at the 2013 Nations Cup when Burkina Faso finished as runners-up, has not played for his country since the German manager took charge of the Stallions.
But the 62-year-old has included the winger in his 24-man squad for the Group D fixture on 5 September.
I'm sure we'll see him playing for his country again which will be exciting, but right now the ball is in his court
And Rohr said he hopes the inclusion of Pitroipa, who plays for Al Nasr in the United Arab Emirates, will benefit the team.
"He's been unavailable for different reasons like club engagements and injury but I'd be hoping [to have him for the qualifiers] because he brings a lot to the team," Rohr told the local media.
"It is no secret that a fully fit and motivated Pitroipa is every coach's joy and only a few managers would deny that.
"I'm sure we'll see him playing for his country again which will be exciting, but right now the ball is in his court."
Rohr has also included brothers Alain and Bertrand Traore - despite the latter yet to make an appearance for Chelsea this season.
There is a maiden call-up for Algeria-based Patrick Malo and a recall for veteran defender Paul Koulibaly.
The squad will report for a three-day camp in Paris on 29 August before flying out to Johannesburg, South Africa four days later.
Rohr also revealed that the Stallions will travel by road from South Africa to the capital Gaborone on 2 September before the hour-long drive to match venue Lobatse on the eve of the game.
Burkina Faso made a strong start to their qualification campaign in Ouagadougou, beating Comoros Islands 2-0 in their Group D opener in June.
Burkina Faso squad:
Goalkeepers: Moussa Germain Sanou (Beauvais, France), Abdoulaye Soulama (Hearts of Oak, Ghana), Baba Zongo (EFO)
Defenders: Bakary Koné (Lyon, France), Steeve Yago (Toulouse, France), Mohamed Koffi (Zamalek, Egypt), Issoufou Dayo (RSB, Morocco), Narcisse Bambara (Universitatea Cluj, Romania), Pierre Daila (Stade Malien, Mali), Paul Koulibaly (Horoya AC, Guinea)

Question: A woman suffered "severe" injuries when she was mauled by her son's dog while walking it for him as a favour, police said.

The animal, described by police as a pit bull, attacked the 52-year-old in Holwick Road, Northern Moor, Manchester at 20:25 GMT on Wednesday.
She suffered injuries to her right arm. A 34-year-old man who helped fight off the dog also suffered "numerous bites".
A witness said about 20 people were "whacking the dog to get it off them".
Jade Royle, 21, said: "It was horrible, all the neighbours were out.
"Everyone was screaming. It was scary. She is very lucky to be alive."
The woman and the man were taken to Wythenshawe Hospital and she has undergone surgery.
The owner of the dog has agreed to have it put down and an investigation was "ongoing", police said.
Det Sgt Sandra Callender of Greater Manchester Police said: "It took a number of people to restrain the dog until police arrived and I would like to personally thank them for their actions.
"Had they not helped this woman and held on to the dog until we arrived then we could possibly have seen more injuries."

The animal was left "hiding and scared stiff" after the incident on Beechwood Avenue at about 20:00 GMT on Monday.
Witnesses told police some youths chased and cornered the animal before encouraging the dog to attack it.
This animal, which received dog bites to its body, was taken away by the RSPCA for treatment. Cleveland Police has appealed for information.

Question: Hearts return to Tynecastle for next week's second leg of their Europa League second round qualifier against Birkirkara on the back of a goalless draw in the Maltese heat.

This is part of a news article. Represent it to retrieve the first (missing) sentence of the article.

Captain Alim Ozturk went the closest to a winner but his long-range effort crashed off the crossbar.
Conor Sammon did find the net but the flag was raised for offside.
Callum Paterson twice went close in the second half with a shot and a header, but they could not find a winner.
The game began with the temperature gauge hitting 30C, however Robbie Neilson's side thought they had the perfect start after just three minutes.
Sammon latched onto a through-pass from Prince Buaben before firing the ball across the goalkeeper and into the net only for the far-side assistant to flag for offside.
The home side were awarded a free-kick around 20 yards from goal on the angle and Srdan Dimitrov curled the ball towards goal at pace, but Jack Hamilton did well to save at the second attempt.
Hearts continued to dominate possession and Ozturk floated a free-kick towards the back post, but Miroslav Kopric in the home goal punched the ball clear.
Jamie Walker was teasing the Birkirkara full-back Cain Attard at every opportunity and the defender was caught napping when the Hearts winger ghosted in, but his header was straight at Kopric.
The second period continued in the same vein with Hearts pushing forward at every opportunity.
Patterson forced Kopric into a diving save with a header from a Walker corner.
There were shouts for a Hearts penalty by the travelling fans when Arnaud Djoum tumbled inside the box after a challenge by Emerson, but the Bulgarian referee waved play on.
On a rare venture forward Attard found himself driving towards the Hearts goal but his effort was well wide of Hamilton.
Ozturk is well known for his long-range efforts and only the crossbar denied the Tynecastle defender the opener from 40 yards out.
Another close call for the home side - who were knocked out by West Ham on penalties at this stage last season - came when Paterson volleyed inches wide from 12 yards with the goalkeeper stranded.
Substitute Sam Nicholson provided a chance for the opener when he fired the ball across for Juanma, but the striker took the wrong option and the chance was gone, with the game ending goalless and setting up a Tynecastle thriller next Thursday.

The Welsh Premier League side were held to a goalless draw in the first leg, but Callum Morris' first-half winner in Fredrikstad secured a famous victory in the club's first European campaign.
Both sides later had players red carded as Stabæk's Kamal Issah and the Nomads' John Disney were sent off.
Connah's Quay will play Serbian side Vojvodina in the next round.
The second qualifying round first leg will take place on 14 July, with the second leg to follow a week later.

Marvin Couson, 39, was wounded at the Lime in London bar in Shoreditch in May 2002. He was left unable to communicate or leave his bed, and died on 8 August.
Police have launched a murder investigation and appealed for witnesses to come forward.
Mr Couson, who suffered injuries to his internal organs, was cared for at the Royal Hospital for Neuro-Disability.
About 600 people were at the bar on 12 May 2002 when police were called to reports of gunfire. They found Mr Couson lying on the ground outside with a gunshot wound to the chest.
A man was arrested during the police investigation, but later released with no further action.
Det Ch Insp Noel McHugh said: "For 13 years Marvin's family have been at his bedside and now, tragically, he has succumbed to the injuries he suffered.
"We have launched a full murder investigation and, despite the passage of time, are committed to finding the person who shot Marvin that night."
He added: "We know there are potential witnesses who did not speak to police at the time and I would ask them to now please come forward with any information, no matter how small. Do not assume that someone else will contact police."
Until a change in the law in 1996, a murder was only deemed to have been committed if the victim died within a year and a day.

Question: A lock of hair snipped from the head of John Lennon 50 years ago has fetched $35,000 (£25,000) at auction in the US.

The four-inch (10cm) lock was kept by a German barber who gave him a trim as he was about to film How I Won The War in 1966.
The unnamed buyer was a British-based collector of memorabilia, auctioneers said.
"This is the largest lock of Lennon's hair ever sold at auction," Heritage Auction in Dallas, Texas, said.
Spokesman Garry Schrum said the bidder got a "good chunk of Lennon's hair", adding: "It was a good size with quite a lot of strands."
Lennon's locks were chopped by Klaus Baruck in Hamburg, Germany, just before the rocker's starring role as Gripweed in Richard Lester's dark comedy about a British army platoon and their misadventures in World War II.
The haircut took place just a month after the release of the band's legendary 1966 Revolver album.

Harrison played the 1962 Rickenbacker 425 guitar on British TV shows like Ready Steady Go! in 1963, prior to the band's US invasion in 1964.
The Beatle, who died in 2001, also used the instrument during the recording of I Want to Hold Your Hand and This Boy.
He bought the guitar during a visit to the US.
Its pre-sale estimate was up to $600,000 (£356,000) said auction house Julien's.
It topped the previous sale of a VOX guitar played by both Harrison and Lennon in May last year which fetched £269,000) but fell far short of the record $965,000 (£591,000) set by a Bob Dylan guitar in December.
The auction also included a handwritten placard with doodles signed by John Lennon and Yoko Ono from their 1969 anti-war protest in Montreal, which fetched $187,000 (£111,000).
A Hofner bass guitar rented by Sir Paul McCartney in the mid-1960s sold for $125,000 (£74,000).
A white jumpsuit worn by Elvis Presley during a 1971 concert fetched $197,000 (£117,000).

Question: A vast, previously unrecognised canyon system could be hidden under the Antarctic ice sheet.

Represent the news to retrieve its missing first sentence!

Hints of its presence are seen in the shape of the white continent's surface, in a largely unexplored region called Princess Elizabeth Land.
If confirmed by a proper geophysical survey - now under way - the winding canyon network would be over 1,000km long and in places as much as 1km deep.
These dimensions would make it bigger than the famous Grand Canyon in the US.
"We know from other areas of Antarctica that the shape of the ice surface is obviously dependent on the shape of the landscape underneath - because the ice is flowing over that landscape," explained Dr Stewart Jamieson, from Durham University, UK.
"When we look in Princess Elizabeth Land with satellite data, there seem to be some linear features in the surface ice that to us look very reminiscent of a canyon.
"We have traced these faint lineations from the centre of Princess Elizabeth Land all the way to the coast, off to the north. It's a pretty substantial system," he told BBC News.
There are suggestions also that the canyon network is connected to a previously undiscovered subglacial lake.
If confirmed, this lake would likely cover up to 1,250 square km, which is about 80 times as big as Windermere, England's largest lake.
The initial interpretation of a canyon system is supported by radar data that has been gathered in a couple of locations.
Radar sees through the ice layers to the hard rockbed below.
The story is consistent, says team-member Prof Martin Siegert, from Imperial College London, UK, said.
"Discovering a gigantic new chasm that dwarfs the Grand Canyon is a tantalising prospect.
"Geoscientists on Antarctica are carrying out experiments to confirm what we think we are seeing from the initial data, and we hope to announce our findings at a meeting of the ICECAP2 collaboration, at Imperial, later in 2016."
Most of Antarctica has now been covered by full geophysical surveys that have imaged the continent's underlying topography.
But there remain two "Poles of Ignorance" that need to be filled in. One of these is Princess Elizabeth Land; the other is the Recovery Basin.
Both are in East Antarctica, and both are now the targets of intense study.
International teams - comprising scientists from the US, the UK, Australia, China and other nations - are flying sensors back and forth across thousands of square kilometres of ice surface.
When complete, Antarctic researchers will have a comprehensive view of what the landscape really looks like beneath all its accumulated ice. This is fundamental knowledge in trying to understand how the continent might react in a warming world.
"If we don't know the shape of the rockbed, we cannot confidently build models that will produce sensible behaviours in the ice," asserted Dr Jamieson.
The latest research is published in Geology journal.

Question: A Florida state senator has resigned amid backlash over reports that he used racial slurs over drinks with African-American colleagues.

Represent the news article to find a single sentence that could be used as a summary

Miami Republican Frank Artiles reportedly insulted two black senators during a bar chat at the Governors Club in Tallahassee.
Mr Artiles apologised for the incident on Wednesday, but the two lawmakers and critics called for his resignation.
In a letter to the Senate president, Mr Artiles called himself a "distraction".
"My actions and my presence in government is now a distraction to my colleagues, the legislative process, and the citizens of our great State," he wrote to Senate President Joe Negron.
"I am responsible and I am accountable and effective immediately, I am resigning from the Florida State Senate."
"It's clear there are consequences to every action, and in this area, I will need time for personal reflection and growth," he added.
According to the Miami Herald, the incident began after 22:00 local time on Monday over drinks at the members-only club, located just steps from the State Capitol.
A lawmaker approached Mr Artiles to ask if his objections to a bill she had filed were political payback for her questions about one of his previous bills.
Mr Artiles reportedly used insults and profanity against African-American Senators Audrey Gibson of Jacksonville and Perry Thurston of Fort Lauderdale.
He allegedly referred to Ms Gibson as a "bitch" and a "girl".
According to witnesses, Mr Artiles also said Republican Senate President Joe Negron, who is white, owed his position to "six [racial slur]".
It is unclear who he was referring to because the chamber's black senators are all Democrats, none of whom voted for Mr Negron.
During Monday night's discussion, Mr Artiles reportedly sought to justify his use of the n-word, insisting he intended a slang pronunciation that he thought was not offensive.
But Mr Negron ordered an investigation and forced Mr Artiles to apologise on Wednesday.
Afterwards, Mr Artiles told reporters he would not resign and would "file for 2018 and win my election", the Miami Herald reported.
On Thursday, Mr Artiles added he was stepping down to protect his family.
"While I take full responsibility for using language that was vulgar and inappropriate, my family has fallen victim to a political process that can distort the truth for the sole purpose of political gain," he said.
