Labour's Shadow Home Secretary Yvette Cooper has said that it "is racist to stir up fears about Romanians" as she responded to Ukip leader Nigel Farage's comments in a radio interview.
She told ITV News: "It's not racist to be worried about immigration or to want stronger controls, but it is racist to some how stir up fears about Romanians living next door. So Ukip should say they were wrong on that.
"But we have also got to deal with the practical issues around jobs and wages, and the practical proposals we are putting forward."
