The European Commission warned that it will be checking the legality of the Government's rules on how long EU jobseekers must wait to claim benefits.
"For the moment it is too early to say whether the new rules are compliant," said Jonathan Todd, spokesman for EU Employment Commissioner Laszlo Andor, who is currently embroiled in a war of words with David Cameron over imminent unrestricted Romanian and Bulgarian immigration to the UK.
"[Numerous] studies show that the vast majority of EU nationals go to other member states to work and that they usually pay more in tax and social security contributions than they receive in benefits because more of them tend to be of working age compared with the population of the host country."
