Labour calls for Iain Duncan Smith to be sacked over unemployment failures Lastly, the Work Capability Assessment, which checks whether disabled people are able to do any work, has been put in special measures because of so many mistakes, Mr Byrne said. "I hope the Prime Minister has another reshuffle soon," the Labour MP said. The office of Mr Duncan Smith today said the remarks were a compliment as they show his reforms to welfare are a threat to Labour. A spokesman for the Work and Pensions Secretary said: "I am not surprised Liam Byrne would like Iain Duncan Smith to be moved in the next reshuffle - Iain's reforms are hugely popular and he's doing a brilliant job at sorting out the mess Labour left behind. This is a real compliment from Liam and further testimony that the Labour Party are running scared on welfare because they know they are completely out of touch with the public on this issue. The welfare party have voted against £83 billion worth of welfare savings and now we know that their paymasters Unite are fully supportive of policies like the benefit cap, which Liam Byrne and Ed Miliband oppose. Not surprisingly, the shadow work and pensions secretary has nothing of substance to say about what Labour would do instead. Conservatives hope Mr Byrne is not moved from his role in any Labour reshuffle, she added. The Department of Work and Pensions is in charge of some of the most difficult and complex reforms being attempted by the Government. Earlier this week, the department was criticised when a review of the Work Capability Assessment found almost half of the controversial "fit for work" tests carried out on disabled people are of "unacceptably" poor quality. The Prime Minister said he was "concerned" by the failings of Atos, the company which carries out the tests, adding that new providers are being brought in to administer the scheme. The government also admitted its flagship scheme to tackle youth unemployment has found just 4,600 placements for 18 to 24 year olds who have been out of work for more than six months. Nick Clegg, the Deputy Prime Minister, announced the Youth Contract 18 months ago with the intention of helping 160,000 unemployed young people find work.
