In full: Prime Minister's Questions

Hello and welcome to our live coverage of prime minister's questions. We'll be bringing you all the latest from the Commons as David Cameron takes questions from Labour leader Ed Miliband and other MPs. We'll start with analysis from BBC Two's Daily Politics - where former Labour chancellor Alistair Darling and former Conservative home secretary Michael Howard will be joining Andrew the team to discuss events.

What issues might be raised this week? The Greek debt crisis is dominating the news - with MPs divided over the future of the eurozone. Rioting in east Belfast is also high on the news agenda but perhaps Mr Miliband will ask about Tuesday's announcement on sentencing and legal aid reforms instead.

Lord Howard begins by saying Justice Secretary Ken Clarke - who has had a rough time in the press over his rethink on sentencing discounts for early guilty pleas - doesn't need anyone to feel sorry for him.

A note of support from the Labour benches? Alistair Darling says Ken Clarke came up with "some interesting ideas" on prisons - but he says there is no doubt that Tuesday's decision to ditch the 50% discount on sentences for criminals who plead guilty early was a U-turn. The former chancellor says the Treasury will be worried it is not going to get savings from the policy that had been promised.

Labour has an opposition day debate in the Commons later - on the economy. Lord Howard - a former shadow chancellor - says it's too early to make judgements, the government has a five-year project in mind. Employment figures have been good, he says, the UK has kept credibility on the international markets - he points out the coalition had an "awful inheritance" economically.

Former Labour chancellor Alistair Darling says the fear of cuts might well be depressing economic activity. He warns against "talking down" economic activity.

Does Alistair Darling agree with his successor - shadow chancellor Ed Balls's suggestion that VAT should be cut temporarily to boost the economy? He says Mr Balls is not alone in suggesting such things - and says he has his "complete support" in his argument that George Osborne's approach runs the risk of derailing economic growth. He doesn't confirm whether he agrees or disagrees on the VAT issue but repeats that he "agrees with his analysis".

Lord Howard quips: "That sounds like a 'no' to me."

Lord Howard says Greece is an "object lesson in what happens when a government spends more than it can afford" - he says he was warning back in 2005 Labour was spending too much.

The Commons is about half full as Scottish Secretary Michael Moore takes MPs' questions on Scotland ahead of the main event - no sign of the PM or Ed Miliband in their seats just yet.

Conservative MEP Daniel Hannan is on the Daily Politics, talking about the Greek crisis. He says previous bailouts have been "actively harmful" as Greece now owes more money.

Speaker John Bercow ticks off MPs for having private conversations in the chamber. MPs seem to be in a noisy mood ahead of PMQs.

The famous green Commons benches are now packed. Michael Moore is still on his feet for Scotland Questions but David Cameron is now in place beside the despatch box.

tweets: Ed Miliband should well point at Cameron and say "this lady IS for turning" during PMQs.

David Cameron begins by paying tribute to soldiers killed in Afghanistan - Gareth Bellingham, Andrew Found and Lloyd Newell

Labour's Kerry McCarthy begins by asking about the effects of cuts on child poverty - Mr Cameron says the government has put more money into tax credits for the poorest families, among other measures. He gets cheers as he says the government inherited a "mess" from Labour.

The Greek debt crisis is raised early - the PM stresses again the UK will not be involved in an EU bailout.

Ed Miliband repeats the tributes to soldiers killed in Afghanistan this week - he says it's Armed Forces Day this Saturday and a chance to recognise the efforts of servicemen and women. His first question is about concerns about the mission in Libya.

Mr Cameron says the Libya mission is funded out of the Treasury reserve fund - and will not put extra pressures on the Ministry of Defence budget. He says pressure is building on Libyan leader Col Gaddafi. Mr Miliband says Labour is fully supportive of the mission - but concerns expressed by high-ranking forces personnel suggest the defence cuts need reviewing.

Mr Miliband presses the issue of defence cuts - Mr Cameron says the strategic defence review had recognised the possibility that two sets of military action might be fought at the same time. He says Labour didn't have a review for 10 years but was now suggesting there should be two defence reviews in one year.

Mr Miliband says there's "clear concern" about the issue in the military - there is laughter as he says he raises the issue in "all sincerity". He also criticises Mr Cameron's comments about military chief who raised concerns - suggesting they were "crass". The PM says he was just making the point that when at war, you have to be careful about what you say.

A subdued session so far - often the case when the subject of the UK's military operations are being discussed. The noise levels return to normal as Labour's Mary Glindon raises government U-turns.

The PM quips: "I'm afraid I didn't get all of that". The Speaker tells off noisy government backbenchers.

BBC Political Correspondent Ben Geoghegan says: Ed Miliband was treading the line carefully - supporting the military action in Libya, but also reflecting concerns from some military chiefs about whether a campaign beyond six months is sustainable. David Cameron needs to keep up the pressure on Gadaffi so no weakening of the determination to stay in Libya "for as long as it takes".

Conservative Iain Stewart raises the issue of homophobia in sport - a friendly question for Mr Cameron who is hosting a Downing Street reception for gay sports people later on.

On to "runaway fathers" - a speech made by Mr Cameron last week. A Labour MP suggests government cuts will make it harder for single mothers to get child support. Mr Cameron says fathers should not be allowed to abandon their responsibilities.

Ed Miliband returns for his second set of questions - he has opted to have two bites of the cherry this week.

The Labour leader asks about DNA and whether people arrested, but not charged, with rape should be able to have their DNA removed from the database. Is he hoping to force another U-turn on criminal justice?

The Labour leader says thousands of people each year are arrested but not charged on suspicion of rape - but sometimes went on to commit other offences. The Speaker calls "order" as noise levels rise. Mr Cameron says it seems to come as a surprise that he talks to his ministers - after a quip about Ken Clarke - and suggests Mr Miliband does not talk to his own shadow chancellor.

Mr Cameron clearly had his riposte ready when Mr Miliband brought up the subject of justice U-turns.

Mr Miliband suggests it is the PM who has not talked to his ministers before they put forward a policy - he's getting a lot of support from the Labour benches for his line of questioning. He says it's another "careless" policy on crime. The PM suggests Mr Miliband doesn't understand the policy. He says police can apply to keep DNA on the register.

Speaker John Bercow interrupts again to quieten MPs down. Mr Cameron tries to exploit supposed differences between Mr Miliband and Ed Balls, to deflect Mr Miliband's line of attack on Mr Cameron's relations with Ken Clarke. Knockabout stuff but not too enlightening.

MPs calm down as Labour's Valerie Vaz - sister of Keith - asks about epilepsy deaths. The PM says he would be "delighted" to discuss the issue with her and pays tribute to a clinician Ms Vaz wants to bring with her.

Another Conservative MP raises the VAT issue to attack Labour - Mr Cameron is more than happy to oblige, saying a cut would be the "height of insanity" - to cheers from his benches

BBC Political Correspondent Ben Geoghegan says: Speaker asks MPs to take whatever medicine is necessary to calm down. Remember last week he said the public "despises" rowdy sessions. But are they listening ?

A Labour MP says bankers are being helped by the government while families with disabled children are being hit by cuts - Mr Cameron says Labour had voted against measures in the finance bill to penalise people who give themselves loans to dodge taxes.

A rather random interjection in the Greek debt crisis debate. Lib Dem MP Andrew George suggests the UK should give Greece back the Elgin Marbles - Mr Cameron doesn't agree, joking that the short answer is "we haven't lost our marbles".

Labour's John Mann asks about mistakes made in exam papers recently and what will be done to help students who miss out on their university places - Mr Cameron says he is quite right to raise the issue and he has been meeting with officials to see what can be done to ensure it "does not happen again".

On to pensions - Mr Cameron says proposals are not about "attacking or degrading public sector pensions". He says he needs to win the argument on the basis of "fairness" - unions are planning widespread strikes over the issue.

Labour MP Catherine McKinnell asks about a constituent left waiting for an operation - Mr Cameron says he is happy to look at the case as the government has not changed waiting list targets.

Conservative backbencher Douglas Carswell asks about an EU bailout facility that the UK is signed up to - the PM notes that the MP is pursuing the issue with "dogged tenacity".

Newly-elected Labour MP for Barnsley Central - former Royal Marine Dan Jarvis - pays tribute to the fallen in Afghanistan and calls for "new chapter" to be opened in the defence review. Mr Cameron says the review is working and "we should stick with it".

Labour's Wayne David suggests Secretary of State for Wales Cheryl Gillan had said she was prepared to be sacked over the government's plans for high speed rail - he asks whether the PM will take her up on her offer? Mr Cameron laughs and says she is doing a good job.

The PM is invited to visit Rochdale - birthplace of the Co-op - to "show support of mutualism" by the local Labour MP - Mr Cameron jokes about prime ministers' record for visiting Rochdale - a reference to the infamous Gillian Duffy incident involving Gordon Brown during last year's election campaign.

Labour's Luciana Berger asks about carbon reductions - she suggests a Tory MEP is going to scupper a vote in the European Parliament on Thursday. Mr Cameron says the government is committed to a 30% reduction target - he criticises Labour MEPs' record on voting - adding they rejected a proposal to scrap first class air travel for MEPs.

A final question on prisons policy from a Conservative MP - Mr Cameron says the government inherited an expensive system that did not work - and with that, the session wraps up for this week

Over in the Daily Politics studio, Lord Howard says those MPs who ask to re-open the strategic defence review need to explain where the money is going to come from.

BBC Political Correspondent Ben Geoghegan says: After last week's success in wrongfooting David Cameron with questions on cancer patients, Ed Miliband once again focused on issues that haven't been dominating the headlines. Today, he chose the DNA database and the government's proposal to take names off it if rape suspects aren't charged. Labour want DNA to be held on the database. The Labour leader is also trying to catch the PM out on policy detail - you could hear Labour MPs trying to taunt Mr Cameron shouting, "he hasn't read it" as Mr Cameron gave his answer.

Kevin Maguire, the Mirror journalist, tells the Daily Politics it is not certain Ed Miliband will lead Labour into the next election - he's effectively on probation and some MPs who backed him for the leadership regret it, he says. Alistair Darling - who supported Ed's brother David for the leadership - says he will lead the party into the next election. He says he doesn't have time for people who "murmur in the background".

Alistair Darling says Labour would have had to do a strategic defence and there had been problems at the Ministry of Defence - governments always expected to do less on defence but ended up doing more, he says.

Lord Howard says if action had not been taken in Libya there would have been a "bloodbath in Benghazi" - he says Ed Miliband had not departed from supporting the action taken.

There's a bit of banter about Tory MP Tracey Crouch, who has been booted off the Parliamentary 11-a-side football team due to FA rules on women playing. She gets support from lifelong Liverpool fan Lord Howard who says the rules should change.

Well the Commons chamber has largely emptied out and as things are quietening down, we'll wrap up our coverage here. Thanks for joining us and for all your comments, we'll be back next week, same time, same place, with another prime minister's questions session.
