DAVID CAMERON will hit a “legal brick wall” in his bid to deprive EU nationals of in-work benefits, TUC leader Frances O’Grady predicted yesterday.

Ms O’Grady said the Prime Minister’s plan to stop EU citizens accessing benefits until they have lived in Britain for four years would breach “discrimination, human rights and freedom of movement principles.”

She said: “What I think is worrying about this is the risk of discrimination on the basis of national origin and more generally a world view that suggests that treating one group of workers worse than another group is somehow going to help us in the big challenges that we face.”
