Liam Fox, former Tory defence secretary, seeks assurances that David Cameron would not agree to scrap the renewal of Britain's Trident nuclear weapons system in any future coalition negotiations. Mr Cameron reaffirms his commitment to the deterrent and says Labour needs to rule out any possibility of a coalition with the SNP, who have said the scrapping of Trident would be a red line in any coalition negotiations.

Lib Dem David Ward asks the PM whether he feels his and Ed Miliband's behaviour at Prime Minister's Questions either enhances or damages the image of Parliament. In his reply, the prime minister acknowledges it is "inevitably a robust exchange" but says there is always room for improvement. PMQs has an important function, in that it holds government to account, he adds.

Labour backbencher David Winnick says he doesn't want to be personal but... the PM "doesn't understand" the lives of people who try to live on modest incomes. The Conservatives remain the party of the rich and privileged, he adds. David Cameron responds that 1.85 million more people are now in work as a result of the government's policies, as he defends his record in office.

On to backbench exchanges now. Barry Gardiner, the Labour MP for Brent North, uses his question to raise concerns about targets for cancer referrals. David Cameron tells him there has been a 50% increase in cancer referrals, and stresses the importance of early diagnosis. He also underlines the need to keep on with the Cancer Drugs Fund.

Ed Miliband tries once again, asking the PM if he will commit to the debates - which is met with the same reply from the PM, who adds that Mr Miliband wants to avoid debating with the Greens. This gives him the chance to joke that Labour's leader had seen Natalie Bennett's "car crash" interview last week as a "master class". That brings the leaders' exchanges to a close.

"So it's all about leadership?" responds Ed Miliband - which gets cheers from the Tory backbenchers. The Labour leader changes subjects, and goes on the attack over TV election debates, asking the PM if he will commit to the proposed head-to-head debate with him on 30 April. Mr Cameron does not say he will take part, saying "we're having a debate now" and says Miliband can't talk about jobs or the economy because of the government's success.

The PM takes a swipe at Ed Miliband whom he says Labour MPs do not want to feature on their election leaflets. He asks for a show of hands for those going to feature Mr Miliband on their leaflets. Lots of arms are raised on the Conservative benches.

Parliament

Speaker John Bercow tries to quieten noisy MPs, telling them they should consider what their rowdiness looks like to the public, whose votes they will be seeking soon.
