Firms would not be able to undercut wages by paying agency staff less than permanent staff under a Labour government, Ed Miliband has said.
Writing in the Independent on Sunday, the Labour leader said the party would close a loophole in the law that allowed for differing rates of pay.
Mr Miliband said he wanted to tighten the rules to “stop a race to the bottom with workers coming here from abroad”.
Labour had “changed on immigration” since it lost power in 2010, he added.
Mr Miliband said the cost of living crisis was the most important context for the debate about immigration.
“Low-skill immigration” risked “making the problems of the cost of living crisis worse for those at the sharp end”, he told the newspaper. “It isn’t prejudiced to believe that.”
