Labour MP Fiona Mactaggart says Jeremy Corbyn's leadership of the Labour Party "is probably unsustainable".

She tells BBC Berkshire he wasn't expecting to be leader of the party and so didn't have a strategy to lead it.

She says a "sensible strategy" would be for Mr Corbyn to stand down as leader as it was "causing real problems for the country". She adds disagreements in the party allow the the Conservatives to portray themselves as the "great liberators" for ordinary people in Britain.

She says the Conservative party was better at "getting rid" of leaders who don't lead the party to victory than Labour.

She agrees her comments were a pretty damning indictment of her own party leader. But adds "I didn't quite call for him to stand down".

In Westminster, a political battle is being waged on two fronts.

David Cameron is engaged in what seems to be an increasingly successful campaign to persuade the House of Commons to expand British military air strikes into Syria.

On Thursday, he gave more details of what had been billed as a "comprehensive plan", not just for bombs to fall on the so-called Islamic State's stronghold in Syria, but £1bn for reconstruction; a perhaps optimistic assessment that there are 70,000 moderate forces on the ground with whom we could work; and an increasing confidence that the time is right to join America, France and even Russia in air strikes.

But the government is reliant on some support from the Labour Party to get its way. And Jeremy Corbyn's party is embroiled in an enormous row of its own.

Arriving in Malta for the Commonwealth Heads of Government Meeting (Chogm), the prime minister has been asked whether he is confident he'll win a vote for military action in Syria, especially as Labour leader, Jeremy Corbyn, is against British air-strikes.

Former London Mayor Ken Livingstone has been criticised for suggesting Tony Blair was to blame for the deaths of 52 people in the 7/7 London bombings. Read more here

Speaking on Question Time, Mr Livingstone said the then-prime minister ignored a security service warning two years earlier that invading Iraq would make the UK a terror target.

Labour MP Mike Gapes called the comment "despicable", while Labour backbencher Ian Austin dubbed it a "disgrace".

A Commonwealth unit to target the "scourge" of extremism is being set up, Prime Minister David Cameron has said.

The Commonwealth has a vital role to play in tackling terrorism, he said, as he pledged £5m over five years to help fund the unit.

He is meeting leaders from across the 53-nation group in Malta, where the Commonwealth Heads of Government Meeting (Chogm) is taking place.

The Queen is to open the conference, which takes place once every two years.

BBC Radio 5 Live

Labour MP John Spellar has accused Jeremy Corbyn of undermining the shadow cabinet by trying to pre-empt the outcome of a meeting on Monday, which was meant to establish a common position on air strikes in Syria.

The defence select committee member lashes out at Mr Corbyn's shadow cabinet allies, who share his position on Syria, in an interview with BBC Radio 5 Live.

"How does Jeremy Corbyn and his small group of tiny Trots in the bunker think they've got the unique view on it all?," he said.

"It's absolutely right for him to put that view in the shadow cabinet. It's right for them to discuss it.

"They thought they were going away to resume that discussion on Monday. He's now trying to pre-empt that and whip up a storm inside the party. It is, as I say, unacceptable.

"Certainly, by the way, they should not resign. They should hold onto those places. If anyone should resign after this incident, it should be Jeremy Corbyn."

BBC Breakfast

Diane Abbott, shadow international development secretary, says reports about big divisions over Syria at Thursday's shadow cabinet meeting was "misleading" and "incorrect" saying "more unites us than divides us".

She says the party would make a "collective decision" adding Jeremy Corbyn's views were "well known" and in line with the majority of the party membership. 

She says as leader it was right for him to make his position clear, otherwise he would be accused of lack of leadership.

 She adds: "party members want us to unite behind the leadership"

She doesn't think David Cameron "made the case" for air strikes in Syria.

Shadow Foreign Secretary Hilary Benn says he believes the UK should "play our full part" in the action against IS. 

Speaking on the Today programme he says he believed the question of our own national security was very important, "it is very, very clear the threat that we and other nations face".  

Given the "mortal blow" France had suffered in the attacks on Paris, he said, it was "right that we play our part" in selected, targeted airstrikes.  

Mr Benn said Jeremy Corbyn was "perfectly entitled to express to Labour MPs his view and the conclusion he has reached".  

"I am not going to resign because I am doing my job as Shadow Foreign Secretary," he added.

Mr Benn said every member of the shadow cabinet would think deeply and carefully about their individual decisions and it was right to respect those who take a different view. 

Asked if there would be a free vote he said, "that remains to be seen"... "maybe that is where we end up". 

Mr Benn denied it would be difficult for Mr Corbyn to continue as leader, saying "we are united behind Jeremy".
