David Cameron tells Marr he's "hopeful" of an EU deal in February and referendum is likely after September
He says he'll stay on as PM - and "do everything necessary to make it work" - if UK votes to leave EU
Shadow justice secretary Lord Falconer urges Labour to "come together" after recent reshuffle
Labour MP Alison McGovern has quit a party policy group over differences with the leadership
David Cameron says the government can solve flood problems because of the strong economy it has created. Mr Corbyn speaks about a young couple he had met in York who had been flood victims - provoking laughter from Tory MPs. It is no laughing matter for the couple, says Mr Corbyn.
Assistant editor of The Spectator tweets:
After a further accusation from Jeremy Corbyn of not enough being done on flood protection, David Cameron repeats his line that flood spending has gone up - and then attacks Mr Corbyn over his plans to renationalise the railways. Then he switches to Labour's "three day" reshuffle, saying Mr Corbyn "can't run anything".
The Sun's Westminster correspondent tweets:
David Cameron says it was the wettest December on record - but spending on flood defences has steadily gone up under his premiership. He says lessons have been learned, noting that the army had been sent in much more quickly this time.
Mr Corbyn reads out flood protection schemes he says were cancelled in Leeds, an area hit by bad flooding. Will the full scheme go ahead to protect the city from future flooding?
BuzzFeed political correspondent tweets:
And here is Pat McFadden, listening to the PM quoting him
Jeremy Corbyn attempts to switch focus from Labour turmoil by asking David Cameron what lessons have been learned from the recent floods.
David Cameron is on his feet in the Commons, backing Pat McFadden's stance on terrorism.
BBC Political Editor Laura Kuennssberg says she expects further front bench Labour resignations.
Stephen Doughty says he agrees with Jeremy Corbyn on many issues - but he attacks the behaviour of "some of those around him and on his team" - particularly over the way shadow Europe Minister Pat McFadden was sacked.

Emily Thornberry, who has been appointed shadow defence secretary by Labour leader Jeremy Corbyn, has been given that rarest of things in British politics - a second chance.
The Islington South MP is best known to the public for being forced to resign as Labour's shadow attorney general in November 2014 for tweeting a picture of a white van parked outside a house bedecked with England flags.
Conservative politician Sir Alan Duncan insists junior doctors will not be worse off under the deal being offered by the government, saying it is just a change to the pay structure.
He also takes a swipe at the BMA, saying: "I am not convinced they are negotiating honestly and fairly in the interests of junior doctors."
But a junior doctor, Mei Nortley, says the health service is stretched and junior doctors are being asked to do too much. She adds that she has full confidence in the BMA.
PoliticalHome editor tweets:
Shadow energy secretary Lisa Nandy has cast some doubt on the position set out by John McDonnell this morning, saying "it's not my understanding" that he would be able to disagree from the backbenches.
She said: "I can't imagine Hilary would've accepted a deal to stay in his job if he couldn't speak. What I think they will have agreed is to come to a collective view on the questions of the day."
Labour MP Lisa Nandy says she was "never offered it and I never had a discussion about it," of rumours she was in line to become shadow defence secretary in Jeremy Corbyn's reshuffle.
Emily Thornberry got the job. Read the story of her comeback from the tweet that nearly ended her career here.
House of Commons
Parliament
Just nine hours after yesterday's sitting finished, they're back under way in the Commons with questions to the Secretary of State for Scotland.
The first question for David Mundell is from the SNP on meetings over changes to Scotland's fiscal framework, the way the Scottish government is funded. He says he's "confident" the UK and Scottish governments will be able to achieve a "fair framework".
