We're ending our live coverage of Prime Minister's Questions now, but you can carry on watching the statement on Universal Credit, and the rest of the day's action in Parliament, on the BBC's Democracy Live website. All the key clips and video of the session in full will be added to this page, with some updates later on fall-out from the session.
Commons: Iain Duncan Smith replies to Chris Bryant by calling it the "most pompous, ludicrous statement that I have heard". He said the outline business case for this parliament had been approved. He added that he expected soon to have agreement for the business case for the lifetime of the project.
Commons: Chris Bryant says that the eight different answers given so far to the same question led him to think the House had been misled by a government "involved in a deliberate act of deception".
On the Daily Politics BBC political editor Nick Robinson says both sides could be argued to be right on the NHS statistics' spat. He said David Cameron's figures may not have been wrong but they did not tell the whole story, while Mr Miliband failed to make headway with the "ammunition" he had at his disposal. Experts, he adds, genuinely believe there is a "funding crisis" in the NHS but none of the parties want to talk about alternative funding solutions.
Commons: Labour's Chris Bryant called Mr Duncan Smith's answer a "spectacular instance... of beating about the bush". It's a very simple question, he says, has the DWP business case for Universal Credit been approved by the Chancellor? It is depressing that Mr Duncan Smith and Mr Cameron do not know the difference between an annual budget and a business case, he adds.
On the Daily Politics, the Conservative Liz Truss says Ed Miliband "failed to score" on A&E waiting times but Labour's Emily Thornberry accused the prime minister of "making up statistics as he goes along".
On the Daily Politics, the BBC's political editor Nick Robinson says the terms of the Butler-Sloss inquiry into child abuse will be vital in determining whether the public have confidence in it.
Work and Pensions Secretary Iain Duncan Smith is now answering Labour's urgent question on Universal Credit in the Commons.
