Good morning. Keir Starmer is still in France for the G7 summit but – as Margaret Thatcher discovered on a trip to Paris in November 1990 – acting as a statesman on the world stage does not protect a PM from a leadership challenge at home and, on that front, there has been a small development overnight; Starmer is now being told explicitly he will face a leadership challenge next week if he does not agree a timetable to stand down after the Makerfield byelection tomorrow.

This has always been implicit, but last night Wes Streeting, the former health secretary who wants to launch a leadership bid, said it out loud.

Streeting was doing media all day after giving a speech on his economic vision (which he calls progressive capitalism). Asked about the leadership at his speech event in the morning, he stressed that he wanted Starmer to set a timetable for his departure. By the time he came to speak to broadcasters in the evening, he was more explicit.

In an interview with Cathy Newman for on her Sky News show, asked what he would do if Starmer did not agree voluntarily to set a timetable for his departure, Streeting replied:

We can’t go on with this uncertainty. I think we will inevitably end up in a contest.

When Newman asked if he meant next week, Streeting replied:

I’ve given you my answer.

Newman pressed him again. “Next week the prime minister, you expect, will face a challenge?” And Streeting replied: “Yeah.”

A bit later, being interviewed by Victoria Derbyshire on Newsnight, Streeting gave a very similar answer. Asked about the timing of a challenge, Streeting said he was “not going get into, ‘is it Monday, is it Tuesday?’” But when Derbyshire asked if he meant “in the not too distant future”, Streeting replied: “We can’t go on with this.”

He also said he was confident he had the 81 names of Labour MPs he would need to launch a challenge.

This morning Starmer has responded. In an interview with Sky News, he said that he would offer Andy Burnham, the Greater Manchester mayor who is expected to win the Makerfield byelection tomorrow, a cabinet job. Burnham, of course, not Streeting, is the real threat to the PM, because he is the person with most support from Labour MPs, and Labour members, to replace Starmer.

Starmer told Sky’s Beth Rigby: “Yes, I want him to have a big role in government”.

He went on:

Well, I’m sure I’ll talk to Andy after the weekend, of course I will. I’ve spoken to him many times in recent weeks. And when I came into politics in 2015, it was Andy Burnham’s team that I joined, and we worked very well together.

He’s a huge asset, he’s been a fantastic mayor in Manchester and if he comes back into parliament – I hope he wins in the byelection – he’ll be a fantastic asset for our party and for the country.

This offer is almost certainly too late. Burnham does want “a big role in government”, but it is the one that Starmer is doing himself.

Here is the agenda for the day.

I can’t read all the messages BTL, but if you put “Andrew” in a message aimed at me, I am more likely to see it because I search for posts containing that word.

If you want to flag something up urgently, it is best to use social media. You can reach me on Bluesky at @andrewsparrowgdn.bsky.social. The Guardian has given up posting from its official accounts on X, but individual Guardian journalists are there, I still have my account, and if you message me there at @AndrewSparrow, I will see it and respond if necessary.

I find it very helpful when readers point out mistakes, even minor typos. No error is too small to correct. And I find your questions very interesting too. I can’t promise to reply to them all, but I will try to reply to as many as I can, either BTL or sometimes in the blog.
