Labour's Liam Byrne, the shadow work and pensions secretary, accused Iain Duncan Smith of "failing" and of breaking "every promise he's made." He told ITV News:
"Iain Duncan Smith is failing. His Work Programme is worse than doing nothing, universal credit is descending into universal chaos and half way through the parliament unemployment is up not down and so is the benefits bill.
He's broken every promise he's made. He's running out of excuses and the country is running out of patience."
