Warning : As a result of greater lorry security , cars and motor homes are a prime target for illegal immigrants in Calais who are trying to enter the UK . In a report published today , the Commons home affairs committee says migrants trying to reach the ‘ El Dorado ’ of Britain are being caught at a rate of 100 a day.At the same time , the number gathering in squalid camps around Calais has almost doubled to 2,500 in the space of a few months . The committee found evidence of migrants who arrived in the EU via Turkey or Italy making their way to Calais without ‘ encountering any border controls ’ . Its report , titled ‘ Migration failures lead to a crisis in Calais ’ , blamed the Schengen Agreement allowing EU citizens to travel from one member state to another without passport checks . The UK opts out of the agreement , which Margaret Thatcher refused to sign 30 years ago to sneers from fellow European leaders . But even the French authorities have now declared Schengen a ‘ failure ’ . Borders allowing access to the EU are not being properly policed , allowing tens of thousands of people from the likes of Somalia , Sudan , Eritrea and Syria to flood in via Italy , Greece and Turkey . Retired bank manager Sue Taber , 59. came through the Channel Tunnel without realising there was a stowaway illegal immigrant in the back of her car . Fabrice Leggeri , the executive director of European border agency Frontex , has warned that Libya alone has up to a million potential migrants ready to leave for the EU . The number massed at Calais has almost doubled since September from 1,300 to 2,500 . Sir Charles Montgomery , director-general of the Home Office ’ s Border Force , said staff detected 30,180 attempts to enter the UK in the ten months to the end of January . This compared to 18,000 in the entire preceding year . Yet when caught , the migrants were handed over to the French who simply let them go . The MPs say : ‘ We find it bizarre that there are thousands of attempts to enter the UK illegally through Calais , at great cost and inconvenience to business and leisure travellers , transport companies , and hauliers , and yet the people who are caught are simply released back into the French countryside. ’ The Government is helping to fund more security fences around Calais . When she found an illegal immigrant hiding in the back seat of her Fiat Panda after driving home from France , Sue Taber couldn ’ t believe her eyes . Miss Taber thinks the man sneaked into her car when she left it briefly unlocked at Calais in September last year . Discovering him upon arrival in Kent , Miss Taber told the man ‘ in no uncertain terms ’ to ‘ get lost ’ . She said at the time : ‘ I ’ ve got a Fiat Panda for goodness sake , with two dogs in the back . 'And I ’ ve managed to get though passport control and everything else with a stowaway on board. ’ But the report says there are fears that as security around freight traffic increases , migrants ‘ will adapt to hiding in a wider variety of vehicles , including private cars or caravans ’ . The home affairs committee warns : ‘ Schengen was intended to allow free movement , but not the free movement of illegal migrants . It was based on the assumption that the external border would be secure. ’ Committee chairman Keith Vaz said : ‘ The crisis in Calais is a direct result of the soft EU external border in the Southern Mediterranean and the Greek-Turkish border. ’ The MPs also cast doubt on the Home Office ’ s ability to carry out new exit checks on everybody leaving the country from April 8 . Ferry operators have warned the measure could create travel chaos for passengers and long queues . The MPs said they expected ministers to agree a series of exemptions – such as not checking the passports of British tourists leaving by coach . A Home Office spokesman said it had committed £12million to help reinforce security at Calais , ‘ including installing security fencing and improving the flow of traffic to reduce the risk of queuing vehicles being targeted by migrants ’ .
Immigrants make it across the entire EU without a single border check . Due to heightened lorry security , many try to stow away in cars . British tourists are being warned they might be targeted in Sudan .
