When Keir Starmer faces MPs today, he might be quizzed over the long-awaited publication of the defence investment plan.

Despite his resignation as prime minister, the plan will be published ahead of next month's Nato summit.

That's despite the proposals triggering the resignations of two ministers earlier this month - Defence Secretary John Healey and Armed Forces Minister Al Carns (who could still enter the contest to replace Starmer - see our previous post).

The decision to press ahead with the defence plans could cause tension with Starmer's successor.

Andy Burnham and his team have been discussing that with Healey - who warned when he resigned that the PM's plan "well short of what is required".

Speaking on Tuesday in the House of Commons, Chancellor Rachel Reeves confirmed the plan would be published before the Nato summit n 7 July, and said it would "involve more money, spent more effectively and meet the scale of the challenges we face".

The prime minister's chief secretary Darren Jones might have ruled himself out of the Labour leadership contest - but former Armed Forces Minister Al Carns could still challenge Andy Burnham.

Speaking to BBC Newsnight on Tuesday, Carns insisted he is "pretty serious" in considering a leadership bid, but wants to "see behind Andy Burnham what the policies are" before making a final call.

As a reminder, leadership nominations open on 9 July and run until 16 July. Potential candidates have until then to amass the support of at least 81 Labour MPs to enter the race.

Asked whether he will back Burnham if he agrees with his policies, Carns tells BBC Newsnight: "I think that's a collective view across the Labour Party as a whole."

He explains the party wants to "get behind" Andy but says "we need to see that material before I can make a decision to back anyone".

Another complication removed for Burnhampublished at 07:26 BST

It was already highly likely that Andy Burnham would become the next prime minister and Labour leader.

Arguably Darren Jones’s announcement does not really change that - though he claimed in his interview with Sky News that he might have been able to reach the 81 MPs required for a full leadership election with party members over the summer.

But at the very least it removes a slight complication from Burnham’s path, allowing him to focus more on his plans for government, even if the former defence minister Al Carns is still publicly toying with his own challenge (we'll have more from Carns in our next post).

What’s striking is how candid Jones was that his big concern about Burnham was his plans for the economy.

He said that Burnham had reassured him. The former Manchester mayor is giving a speech on the economy next week which will in part represent his attempt to reassure other MPs.

In addition, this is why the question of who would be his chancellor is so central to the debate in Westminster.

Wes Streeting: Instead of pitching himself for the leadership role, Streeting has backed Burnham - and could be awarded the number two job in British politics.

Ed Miliband: Somesee Miliband as an inflation risk, believing his drive for net zero as energy secretary is partly responsible for the UK's high energy prices compared to other countries. But others think he could gain the confidence of the markets with his "intellect, experience, and authority".

Pat McFadden: He's held shadow Treasury jobs, been a business minister in a Labour government and is the current work and pensions secretary. His experience in the latter could help tackle welfare reform.

Yvette Cooper: She has years of experience in government, and served as chief secretary to the Treasury under Gordon Brown.

The BBC understands that if Andy Burnham becomes prime minister, he is expected to replace Rachel Reeves as chancellor and offer her a more junior cabinet position.

Most Labour MPs assume Reeves will not continue in that role but, as first reported by the Financial Times,, external she is expected to be offered a more junior cabinet position.

A close ally of Burnham told the BBC: "Andy really respects Rachel and I'm confident he'll want her in his top team."

A spokesperson for Burnham said no decisions had been made.

Meanwhile, James Purnell - who served as a minister in Gordon Brown's government between 2007 and 2009 - is expected to be appointed Burnham's Downing Street chief of staff.

As well as working under Labour governments, Purnell has worked at the BBC in various roles including head of corporate planning and, more recently, director of radio and education. He left the corporation in 2020.

Senior cabinet minister Darren Jones has endorsed Andy Burnham for the Labour leadership.

Despite speculation that he would run himself, the chief secretary to the prime minister said that "Andy Burnham is going to be the next prime minister".

Jones, a former deputy to Rachel Reeves at the Treasury, said he had had a "reassuring conversation" with Burnham about economic policy.

He suggested that a full leadership election would be a bad idea but said there were "definitely upwards of 100 MPs who have expressed concern either around a contest or economic policy or who were just feeling pretty depressed off the back of Keir Starmer resigning".

Jones's comments came in an interview with Sky News.

As Keir Starmer prepares to face the Prime Minister's Questions dispatch box today, it's looking increasingly likely Andy Burnham will be the man to replace him.

Burnham could become prime minister by 16 or 17 July - which is now looking increasingly likely, as already-lukewarm bids from leadership rivals have cooled.

Chief Secretary to the Prime Minister Darren Jones was said to be considering a leadership bid. He now tells Sky News: "Andy Burnham is going to be the next prime minister."

"So the question for me," Jones asks, "is, well, what would the benefit be to the country and to the party of a leadership contest?"

Meanwhile former Defence Minister Al Carns told BBC Newsnight on Tuesday that he is considering a contest, and will need to see Burnham's policies "before I can make a decision to back him".

As Starmer prepares to take his final Commons bow, Rachel Reeves's time as chancellor may be limited - the BBC understands Burnham is likely to swap her into a more junior cabinet position if he becomes PM.

As we build up to PMQs at noon, we'll catch you up with a frantic week in politics, and look ahead to how the race to be the UK's next prime minister is playing out.
