Ed Miliband yesterday left the door open to a Labour-SNP coalition after the General Election – as the latest polls point to a ‘ Braveheart battalion ’ of nationalists storming Westminster . In a speech to party members in Edinburgh , led by Jim Murphy , the Labour leader ignored calls from his own frontbench , led by Shadow Chancellor Ed Balls and Health Spokesman Andy Burnham , to rule out a deal with Nicola Sturgeon ’ s party . Last week a poll by Tory peer Lord Ashcroft put the SNP on track to increase its representation at Westminster to 56 of Scotland ’ s 59 seats , up from just six seats now . Scroll down for video . In a speech led by Jim Murphy ( left ) , Ed Miliband ( right ) ignored calls from his own frontbench to rule out a deal with Nicola Sturgeon 's party . This means that dozens of nationalist candidates are knocking on the door of the Commons . They include Tommy Sheppard in Edinburgh East who , as The Mail on Sunday has previously reported , left aggressive messages about the Monarchy during the Royal Wedding – including the line ‘ off with their heads ’ – and Mhairi Black , aged just 20 , who has talked about headbutting her Labour opponents in Paisley . The SNP ’ s projected success could cancel out Labour gains in other parts of the UK , leading to a dead-heat between the two main parties – and allowing nationalists to play ‘ kingmakers ’ . Many Labour MPs think the only way to avert a humiliating collapse is for Mr Miliband to tell voters he won ’ t deal with the nationalists , to persuade anti- Conservative voters that a vote for him is the only way to remove David Cameron from Downing Street . However Mr Miliband barely mentioned the SNP at the Scottish Labour spring conference . The Labour leader said : ‘ The Tories could wreak havoc in Scotland without winning a majority by being in government as the largest party. ’ Tommy Sheppard - Edinburgh East . Sheppard is an unreconstructed republican who tweeted ‘ off with their heads ’ during the Royal Wedding in April 2011 and said ‘ this might be a good time to declare a provisional government ’ . Unreconstructed republican : Tommy Sheppard . Mhairi Black - Paisley and Renfrewshire South . The student , who is tipped to beat the Shadow Foreign Secretary Douglas Alexander at the age of just 20 – which would make her the Britain 's youngest MP – wants to headbutt ‘ fat-cat Labour councillors ’ and tweets about her boozy antics . Future MP ? 20-year-old student Mhairi Black . Paul Monaghan - Caithness , Sutherland and Easter Ross . Monaghan was suspended in 2008 from his job as head of planning and development at Northern Constabulary , a Scottish police force , after circulating an unflattering email about his boss . Paul Monaghan : Caithness , Sutherland and Easter Ross . Martin Docherty - Dunbartonshire West . Docherty issued a call to arms to nationalist supporters in January , with the volunteer activist urging voters to take the opportunity to ‘ hold Westminster ’ s feet to the fire ’ . Martin Docherty : Dunbartonshire West . Tasmina Ahmed-Sheikh - Ochil and South . The ex-soap actress was a Tory and then briefly a Labour party member before she signed up to the SNP . As a Tory she described Alex Salmond as ‘ hopelessly out of his depth ’ . Ex-soap actress : Tasmina Ahmed-Sheikh . Alison Thewliss - Glasgow Central . Thewliss boasted that she used Labour campaign literature to wipe her bottom . The councillor , who could topple former Scottish Labour deputy leader Anas Sarwar , also wrote in 2007 about her Labour rivals : ‘ Can I hope some of them keel over ? ’ Glasgow Central : Alison Thewliss . Phil Boswell - Coatbridge , Chryston and Bellshill . Boswell posted messages on social media last month praising anarchy in Greece . The oil engineer said : ‘ It ’ s about time we did like the Greeks and disempowered the corrupt self-serving establishment parties. ’ Phil Boswell : Coatbridge , Chryston and Bellshill . George Kerevan - East Lothian . The former member of the International Marxist Group told November ’ s SNP conference that the UK has a ‘ disastrous economy whose banking system is an organised criminal conspiracy ’ . George Kerevan : East Lothian . But he failed to spell out whether his own party would be willing to strike a deal with another party if it does not win a majority . Mr Cameron responded by raising the spectre of a left-wing axis between Labour and the SNP . He said : ‘ If you thought the worst outcome for this Election was a Labour government led by Ed Miliband , think again . 'You could end up with a Labour government led by Ed Miliband – propped up by the Scottish National Party – an alliance between the people who want to bankrupt Britain and the people who want to break up Britain . 'And even today , Ed Miliband will not rule out a deal or backing from the SNP . If he cares about this country he should do so. ’ An SNP spokesman said : ‘ The SNP are fielding an excellent team of candidates to give Scotland a powerful voice in the House of Commons . ’
