Thousands of jobless from across the EU could seek to take advantage by moving to Britain at a potential cost of billions, said the Department for Work and Pensions. Chris Grayling, the work minister, said last night: “I am both disappointed and surprised that the commission seems so determined to press ahead with this legal action at a time when Europe faces enormous challenges. It is just extraordinary that they would want to go into battle over an issue that is so politically sensitive.”
