The Sun is reporting, external that Tony Blair, Gordon Brown, Ed Miliband and Neil Kinnock - the only former Labour leaders still alive - are all giving Brighton a wide berth this week.

The Conservatives have put out a response to Jeremy Corbyn's Andrew Marr interview, zeroing in on his comments about Trident (he wants to scrap Britain's nuclear weapons but admits his party may take a different view).

Business Secretary Sajid Javid said: "The Labour leader confirmed that he would weaken our defences by scrapping our independent nuclear deterrent and that he would damage our economy by putting up taxes on jobs, earnings, investment and people's homes.

“This shows the Labour Party are a serious risk to our national security, our economic security and to the security of all working people.”

Green Party MP Caroline Lucas is speaking to Sky News' Murnaghan from Bournemouth where the party is holding its annual conference, She is talking about working together with Labour and other progressives. Ahead of the climate change summit in Paris, she criticises the government's "reckless approach" to environmental issues. She says Britain should be leading the way, not slashing support of the solar industry.

The Spectator's assistant editor, Isabel Hardman, reflects on Mr Corbyn's performance, external on this morning's Andrew Marr show:

Lord Prescott is asked for some advice for Mr Corbyn on becoming a Privy councillor. He makes it quite clear that you don't kneel and kiss the Queen's hand. "You hop - get into hopping - from one chair to the other and brush your lips lightly across her hand," he informs us. But it wasn't an experience he relished. "It's ridiculous, I think we should get rid of it."

Last question from Andrew Neil is whether he'd take a job if one's on offer. "No, I like circulating on the outside," he replies, laughing.

Lord Prescott, former Labour deputy PM, defends Mr Corbyn's leadership, saying he got a bigger mandate than Tony Blair. (He admits he voted for Andy Burnham).

He adds that it would be fair for Mr Corbyn to apologise over the Iraq War if he says "the Labour government got it wrong and I apologise now as the leader".

Asked about his survival chances if mandatory reselection was reintroduced, Mr Leslie says he doubts he would be challenged because of his relations with his local party. The Nottingham East MP adds that any reselection process would be "destructive".

Do you want Mr Corbyn to be PM in 2020? Andrew Neil asks Chris Leslie. He says it's important to give Mr Corbyn and Mr McDonnell some time and let them set out their stall.

Quizzed on his differences with Mr Corbyn, Chris Leslie MP - and former shadow chancellor - says he is adjusting to this "new era". He adds it's best for Jeremy to have a chancellor on the "same wavelength" as him. Asked if John McDonnell will make a good chancellor, he makes a plea to him and the party to tone down some of the aggressive rhetoric.

Sam Coates, of the Times, Helen Lewis of the New Statesman and FT columnist Janan Ganesh are discussing Mr Corbyn's support of unilateral disarmament. Ms Lewis foresees a huge upset for Mr Corbyn if he doesn't get his party's support or potential shadow cabinet resignations if he does. She says it would be very hard for shadow defence secretary Maria Eagle, who said when she took the job she was in favour of keeping Trident, to do news interviews and advocate for its withdrawal.

John Pienaar asks Lisa Nandy about the goverment's plans to bring down the benefit cap. She says "work should pay" but there should be limits on the amount we pay out on benefits. She points out that most of the benefits go to private landlords.

Lisa Nandy, shadow energy secretary, admits she backed Andy Burnham in the leadership race, but now sees a great chance for Jeremy Corbyn. 

She says the future of our energy is about empowering people to develop their own energy. The mood going into conference is about excitement, not concern, she adds.

Mr Watson says there is "huge uncertainty" over UK military action in Syria. He says before any decision, they need to know what the mission and the exit strategy is. On his position, he says "I'm open-mined but deeply sceptical."
