Welfare Reform Minister Lord Freud has issued a "full and unreserved apology" after suggesting that some disabled people are "not worth" the minimum wage - but stopped short of resigning.
The Tory peer said he had been "foolish" in "accepting the premise" of a question posed to him during a fringe event at the Conservative Party conference last month.
Labour will force a Commons vote on Lord Freud's future after David Cameron refused to dismiss him for his controversial suggestion that some disabled workers were "not worth" the minimum wage.
The Conservative peer has kept his job after apologising for the comment, which sparked furore among disability charities and was branded "offensive" by deputy prime minister Nick Clegg.
But Labour has made repeated calls for him to go and will table a motion of no confidence in the welfare minister tomorrow ahead of a vote later this month.
The move came as it emerged that Andrew Selous, a justice minister, told a fringe meeting at the Tory party conference that "disabled people work harder because they're grateful to have a job", according to the Independent.
Questions to be asked over meaning behind Lord Freud's comments relating to disabled workers.
