David Cameron in pledge to restrict benefits for immigrants "I share those concerns," Mr Cameron said as he outlined plans to make Britain less welcoming. In a newspaper article, the Prime Minister also attacked Labour, saying the previous government's failure to take a tougher line when Bulgaria and Romania entered the EU in 2007 led to the current situation. Changes in welfare rules could put the Government on a collision course with the European Commission, which has promise to make sure British rules are "compliant" with EU laws treating Europeans equally. In an article in the Financial Times, Mr Cameron sets out several measures responding to the public's concerns: EU nationals will have to wait three months before claiming any benefits, then only be able to claim for six months. After that, they must prove they have a realistic chance of employment. European migrants who want to claim benefits will have to pass a new "minimum earnings threshold," which will establish how much they are likely to earn in the UK. New arrivals found to be begging or sleeping rough will be thrown out of the country and barred from returning for a year, unless they have a job. Britain will 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. Nick Clegg said the measures were "sensible and reasonable" but Mr Cameron is facing pressure from his party to do more, with 40 backbenchers wanting him to extend controls until 2018. Mr Cameron admitted he cannot do more, but blamed Labour for failing to negotiate a different deal in 2004 and 2007. He said Labour's management of immigration policy has led to Britain's current hostility towards EU migration, saying that the failure to impose controls was a "monumental mistake."
