Prime Minister's Questions - David Cameron v Ed Miliband

Welcome to our live coverage of Prime Minister's Questions. It comes hot on the heels of David Cameron's reshuffle and is his first outing in the Commons since MPs returned from their summer break.

Stick with us for live updates, analysis and your comments as MPs get their first chance to quiz the prime minister on his reshuffle, the state of the economy and whatever else takes their fancy.

Tuesday's shuffling of the ministerial pack should provide a wealth of material for Labour leader Ed Miliband - is Mr Cameron shaping up for a U-turn on a third runway at Heathrow? Is Jeremy Hunt really the right man to take charge of the NHS? Does the arrival of Chris Grayling at justice signal a return of "prison works"? Is the government lurching to the right, as most of the newspapers seem to think?

But most pundits expect the Labour leader to focus instead on the economy and accuse the PM of failing to sack George Osborne with, perhaps, a reference to the Chancellor's rough reception from the audience at the Paralympics the other day.

Here's a little recap on the reshuffle. We saw promotions for Jeremy Hunt, who takes over as Health Secretary and Maria Miller, who goes to fill Mr Hunt's shoes as the new Culture Secretary - her first cabinet job.

Ken Clarke lost his job as Justice Secretary, replaced by Chris Grayling, but he will still attend cabinet as minister without portfolio tasked with a "roving role" as a "wise head" based in the cabinet office.

Former Chief Whip Patrick McLoughlin is taking over the transport brief, which has increased speculation the government may be preparing to drop its opposition to a third runway at Heathrow. Former Transport Secretary Justine Greening, a fierce opponent of Heathrow expansion, has been moved to international development.

Lib Dem David Laws is back as an education minister - two years after resigning as chief secretary to the Treasury after admitting he claimed expenses to pay his partner's rent.

There were changes too in the junior ministerial ranks, with a number of those elected in 2010 getting jobs. Liz Truss, Esther McVey, Anna Soubry, Nick Boles, Daniel Poulter, Sajid Javid, Helen Grant and Matthew Hancock start their new ministerial jobs today.

The latest blog from BBC Political Editor Nick Robinson detects "the hand of George" on the reshuffle.

The Chancellor, George Osborne, wanted to remove obstacles he thought stood in the way of his policies.

New Conservative Party co-chairman Grant Shapps tells the BBC's Daily Politics his predecessor Baroness Warsi was "a very good chairman" but "at some point, you have to move your team around".

Mr Shapps says the new cabinet is all about "delivery".

Francis Maude and Oliver Letwin, a cerebral duo who both emerged unscathed from the reshuffle, are taking Cabinet Office questions in the Commons at the moment, ahead of the main event at midday.

If Ed Miliband is planning to attack George Osborne at Prime Minister's Questions, he may be beaten to the punch by Labour colleague Dennis Skinner, a longstanding thorn in the side of the chancellor, who has the first question on the order paper.

Chloe Smith - the youthful junior minister famously monstered by Jeremy Paxman on Newsnight - gets a big cheer from MPs as she makes her debut in her new role at the Cabinet Office.

Nick Clegg has been out and about this morning with newly returned minister David Laws to promote the pupil premium - one of the Lib Dems' proudest achievements in government. Mr Laws is now an education minister, but also has a "roving brief" across other policy areas.

Jeremy Hunt's promotion to Health Secretary "raised a few eyebrows", admits Lib Dem MP Martin Horwood on the Daily Politics, hastily adding that he will do a good job.

The Commons chamber is now packed as Francis Maude comes to the end of Cabinet Office questions. Cheers from the Tory benches as Mr Cameron takes his seat.

Noise levels are rising in the Commons ahead of PMQs. The Speaker already sounds a little hoarse. Looks like it's going to be a rowdy session.

BBC Political Editor Nick Robinson tells the Daily Politics he is always surprised how tight the coalition is at the top - tighter than many single party governments.

David Cameron begins by paying tribute to soldiers killed in Afghanistan - Lt Andrew Chesterman, Lance Corporal Matthew Smith and Guardsman Jamie Shadrake.

Mr Cameron praises the performance of Britain's Olympic and Paralympic athletes and all the London 2012 volunteers.

Dennis Skinner launches an attack on the "posh boys" in the cabinet and calls for a general election.

Conservative Nadine Dorries is up, not known for her fondness of the PM, she asks about boundary changes and party funding.

Not an easy start for Mr Cameron as he faces two of his biggest critics - Labour's Dennis Skinner and his Tory colleague Nadine Dorries. George Osborne looks more uncomfortable though, after being booed by some MPs as he entered the chamber.

Mr Cameron relies on an old stand-by - "Is that really the best he can do?," he asks Mr Miliband, as he talks up the government's plans.

Mr Cameron takes a swipe at Mr Miliband's macho credentials, accusing of him not standing up to Ed Balls, saying he has to bring the shadow chancellor his coffee every morning. "That's how assertive and butch" he is. Labour seem to enjoy this as much as the coalition benches.

Mr Miliband asks about road building programmes and house building and manages to get a dig in about George Osborne being booed at the Paralympics. All good knockabout stuff.

Mr Cameron denies dithering over planning - the coalition has "radically simplified" the system it inherited from Labour. What has Mr Miliband done over the summer, asks the PM.

"The crimson tide is back," says Mr Miliband somewhat cryptically. It's a reference to Mr Cameron's short fuse. The PM laughs at that but Nick Clegg doesn't look too amused.

Mr Miliband calls for George Osborne - the "part-time chancellor" - to be sacked. "It's the same old faces, the same old policies," says Mr Miliband of the reshuffle.

Mr Cameron says the government is doing great work in difficult economic circumstances and accuses Mr Miliband of leading a weak and divided party. MPs erupt at that - leading the Speaker to step in and calm them down a bit.

Wirral South's Alison McGovern wants to know what the government is doing to help families in poverty in the UK.

Labour's Stephen Timms asks about the visa situation at London Metropolitan University. He says the PM is damaging the UK's reputation. Mr Cameron says there were "real abuses going on".

The first Commons clash of the new term generated more heat than light. Mr Miliband tried several lines of attack and had a few good lines, but any hopes he may have had of pushing the PM into losing his temper were dashed.

Labour's Paul Blomfield says the PM is right to celebrate Britain's Paralympic achievements but raises concerns about cuts to the Disability Living Allowance. Mr Cameron says its been "truly inspiring" to see packed stadiums at the Paralympics, adding the government is not cutting support for disabled people.

Andrew Lansley, the new Commons leader, is looking lost in thought on the front bench. There hasn't been much mention of the health service so far, apart from a glancing reference to new Health Secretary Jeremy Hunt by the Labour leader.

Maria Miller and Theresa Villiers, both newly promoted to the Mr Cameron's top team, are seated in prominent positions on the front bench, just behind the PM. There has been criticism of the lack of women in the new cabinet.

Interesting question from West London Labour MP John McDonnell on Heathrow. Will Mr Cameron rule out a third runway while he is Tory leader. Interesting answer from Mr Cameron - he will not break his manifesto pledge.

And that wraps up PMQs for this week.

The Daily Mail reports that new planning minister, Nick Boles once called countryside campaigners "Luddites".

Is new Tory co-chairman Grant Shapps "butch" enough, asks Andrew Neil on the Daily Politics, a reference to Mr Cameron's dig at the Labour leader's alleged failure to stand up to Ed Balls.

Mr Shapps - predictably enough - suggests we are back to the days of Tony Blair versus Gordon Brown at the top of the Labour Party, with the shadow chancellor treating his leader with thinly-disguised contempt. He doesn't say whether he is "butch" enough though.

Tony Blair's spin doctor Alastair Campbell blogs on the reshuffle saying it has moved the government to the right.

Mr Miliband took a leaf out of Gordon Brown's playbook at PMQs by asking Mr Cameron about what had happened to specific policy initiatives, reckons BBC Political Editor Nick Robinson. Always tricky for the PM - but there was no sign he was wavering on his economic strategy, despite the threat of a third quarter of negative growth, adds our correspondent.

Former Tory cabinet minister John Redwood writes on his website that reshuffles are a bad idea. He wants to see a more "orderly process of management" when it comes to making ministerial changes.

Here's some video of Dennis Skinner taunting Cameron over the reshuffle.

"I don't think we have seen anything quite like that" - Nick Robinson's verdict on Boris Johnson's strongly-worded criticism on a suspected U-turn on a third runway at Heathrow. There was nothing coded about this attack on the PM, says Andrew Neil.

Nick Robinson predicts an independent commission on runway capacity to try to build a cross-party consensus. Mr Cameron would not rule out a third runway at some stage at PMQs, just that he would not break his manifesto commitment not to do it in this Parliament.

So is Boris launching a leadership bid? Grant Shapps is not going to fall into that trap. The London mayor has ruled it out, so we must believe him, he tells the Daily Politics.

Here's a clip Ed Miliband attacking the 'same old faces' in government.

Would Mr Shapps himself be facing the London mayor in a future leadership contest? "Naughty," twinkles the new Tory chairman. So that's not a "no" then...

The Telegraph has a breakdown of where the new cabinet ministers went to university. It says it was a good reshuffle for Cambridge alumni with Chris Grayling and Owen Paterson promoted.

Here's the moment the PM said he "will not break" his Heathrow pledge.

So that wraps up our coverage of the first PMQs of the new Parliamentary season. A noisy, rumbustuous session, with a few new faces on the Tory front bench, but no variation on the fundamentals with the PM and Mr Miliband both sticking doggedly to their economic policies. All eyes now turn to the first meeting of the new cabinet this afternoon. Don't forget to join us next week for PMQs when we'll do it all again.
