David Cameron does not have the 'guts' to restrict migrants, Ukip say László Andor said that the curbs on EU migrants could lead to a "slippery slope" of interferences in the single market and could lead to the UK being viewed as the "nasty country" of Europe. Mr Andor added that the Prime Minister did not give the "full truth" about migration in his article. He said that while Polish migration in recent years was "massively higher" than expected their influx had not caused harm and had benefited the UK economy. He added that Mr Cameron had not made it clear that two thirds of migrants arriving from the UK were from non-EU countries and said more people from Italy and Spain were coming to the UK than from Romania and Bulgaria. Speaking on BBC Radio Four's Toady programme he said: "We would need a more accurate presentation of the reality no under pressure not under such hysteria which sometimes happens in the UK. It is true that migration from countries like Poland in the last decade was higher than expected. It was massively higher but it did not cause damage it actually contributed to the growth of the British country. He added: "It risks presenting the UK as a kind of nasty country in the European Union we don't want that, I think there are much better ways." Nigel Farage added that on issues such as immigration his party is a "psychological" threat to the Conservative party, but suggested that they were a bigger danger to Labour. In some seats they were the only ones who can beat Ed Miliband's party and in the North Ukip is "emerging as a challenger," he claimed. As a result he said that he had "absolutely no doubt" that Labour would offer a referendum on Europe before the next election as the whole political scene was changing as a result of his party. Mr Cameron has promised that when border controls are relaxed in January, allowing Bulgarians and Romanians the right to live and work in the UK, new arrivals will be prevented from claiming some benefits. Speaking to Radio 4"s Today programme, Mr Farage said: "It doesn't sound very tough to me. Under his proposal somebody can come here on January 1 from Romania and within 12 weeks be entitled to unemployment benefit. I think that's outrageous. I wouldn't call that tough. I would say that we are still being far too generous even if he does have the guts to put this in place. He said that the Prime Minister was attempting to "curry favour" on one aspect of the public's concerns and was ignoring the fact that 75 per cent of people do not want the borders taken down. "This does nothing to stop an unrestricted flow of a very large number of unskilled people coming into Britain at a time when we have a million young unemployed people," he said. Mr Cameron's promises include that EU nationals will have to wait three months before claiming any benefits and will then only be able to claim for six months. Those wanting to claim will also have to have a "minimum earnings threshold," which will establish how much they are likely to earn in the UK, and new arrivals found to be begging or sleeping rough will be thrown out of the country for a year unless they have a job. Britain will also try to build support among other EU nations to limit the freedom of people from future EU member states to work and travel freely, until their economy approaches the EU average. Mr Farage denied that Mr Cameron's promises had "shot his fox," claiming that every time he made pledges such as this Ukip saw a surge in their popularity. "That is because people just do not believe this guy," Mr Farage said. This is the man who throughout his whole leadership of the Conservative party has said that free movement of people is an essential part of the single market. He is the biggest cheerleader in Brussels for the EU expanding to take in not just Turkey but Ukraine. Mr Farage denied that his party was jeopardising the European Referendum, their main policy, by taking votes away from the Conservatives - the only party who has pledged an in-out vote. He added: "The trouble with Mr Cameron's pledge, on a referendum, is that we have heard it all before. He is the man who previously gave us a cast iron guarantee that if he became Prime Minister there would be a referendum on the Lisbon treaty, he didn't deliver. If he was sincere he would hold a referendum before the next General Election. He said that the idea that the Ukip vote was purely damaging the Tory party was untrue. "We are certainly a threat psychologically to the Conservative party, massively, because the things we say clearly have huge support amongst Cameron's members," he said.
