Sir Keir Starmer could be ousted as PM within months, two senior Labour MPs tell Sky News

Two senior Labour MPs have suggested the prime minister may have to go within months if the government continues to perform poorly.

Sky News' deputy political editor Sam Coates said his sources - a member of the government and a prominent politician - have "put Sir Keir Starmer on notice".

Both warned that, if Labour performs badly in next May's elections across Wales, Scotland and London, it could mark the end of his time in Downing Street.

Coates added: "The level of unhappiness and despair in parts of the Labour Party is so striking that right now, on the first anniversary, I am hearing from ministers in government that Starmer might have to go in months."

Reform UK is surging in the polls in Wales, while Labour faces a threat from left-wing parties such as the Greens in London.

It comes as the prime minister made it clear that Rachel Reeves has his "complete support" as chancellor and remains integral to his project, Sky News's political editor Beth Rigby understands.

She looked visibly upset during Prime Minister's Questions, with a spokesperson claiming she had been affected by a "personal matter".

A day earlier, Sir Keir's controversial welfare bill was passed despite a sizeable rebellion from Labour MPs, with major U-turns meaning a new £5bn black hole has appeared in the country's finances.

One senior figure told Rigby that the pair were as "as close politically" as any chancellor and prime minister have ever been.

"She is going absolutely nowhere," they added.

Ms Reeves's tears sent markets spiralling, with the value of the pound and long-term government bonds falling sharply.

Later in the day Sir Keir, said Ms Reeves will be chancellor for a "very long time to come".

The prime minister said it was "absolutely wrong" to suggest her tearful appearance in the Commons related to the welfare U-turn.

"It's got nothing to do with politics, nothing to do with what's happened this week. It was a personal matter for her," he said while speaking to the BBC's podcast Political Thinking with Nick Robinson.

"I'm not going to intrude on her privacy by talking to you about that. It is a personal matter."

Asked if she will remain in post, he said: "She will be chancellor by the time this is broadcast, she will be chancellor for a very long time to come, because this project that we've been working on to change the Labour party, to win the election, change the country, that is a project which the chancellor and I've been working on together."

He said Ms Reeves has done a "fantastic job" and added: "She and I work together, we think together. In the past, there have been examples - I won't give any specific - of chancellors and prime ministers who weren't in lockstep. We're in lockstep."

Wes Streeting, the health secretary, also offered a strong defence for the prime minister and chancellor.

He told Sky News this morning that Sir Keir has been "consistently underestimated" and was "of course" safe as prime minister.

And he said Ms Reeves was a "tough character" who was " resilient" and "here to stay".
