Keir Starmer was increasingly confident that he had seen off the immediate threat to his job on Tuesday after a challenge from Wes Streeting failed to materialise despite several of the health secretary’s allies quitting the government.Downing Street insiders suggested that the health secretary did not yet have the required support from the 81 MPs he needed to formally launch a leadership bid after Starmer issued a “put up or shut up” ultimatum to his cabinet.Streeting was due to hold talks with Starmer on Wednesday, at which he was expected to talk candidly about his concerns, with No 10 insiders suggesting he was climbing down from intense speculation that he was on the brink of running.“After all that, it’s looking like Wes may not have the numbers after all,” one loyalist cabinet minister told the Guardian.“I’m pleased and furious at the same time.

The best thing for him now is to come out with some dignity and end the drama.”Starmer’s allies also believe he has seen off a threat from the Greater Manchester mayor, Andy Burnham, for the time being, with one saying: “Andy’s supporters keep saying he’s got a seat.But where is it? It’s not real unless he has one.”However, the prime minister’s fragile authority has been further weakened by the resignation of four ministers – three of them close allies of Streeting – in what appeared to be an orchestrated move.More than 90 Labour MPs have called for him to go.

At a private meeting on Tuesday, Labour-supporting unions were divided over whether to call for Starmer to set out a timetable for his departure, with one source saying there had been a “big fight” among union officials,However, they are understood to have agreed to issue a statement saying that Starmer would not lead the party into the next election, despite GMB and Community arguing it was not in the best interests of the unions to get involved in any leadership drama,“Labour’s affiliated unions have been clear that Labour cannot continue on its current path,Whilst we recognise progress has been made … the results at the election last week were devastating,” a leaked copy of the statement said,“Labour is not doing enough to deliver the change that working people voted for at the general election … It’s clear that the prime minister will not lead Labour into the next election, and at some stage a plan will have to be put in place for the election of a new leader.

”Sources also told the Guardian that Ed Miliband, who has privately suggested to Starmer that he should consider setting out a timeline for his departure, had been prepared to run for leader himself if Streeting had gone over the top.Senior Labour figures said Miliband, the energy secretary, who allies say saw himself as kingmaker rather than leadership contender, would have struck a deal with Angela Rayner and Louise Haigh, chair of the Tribune group, for one of them to run as the soft-left candidate, in the event Burnham did not.Sources close to Miliband on Tuesday night, however, denied he is preparing to run for leadership if Starmer steps down, calling it “mischief making”.Earlier on Tuesday, a defiant Starmer told his cabinet he would fight on as prime minister after a turbulent few days in the wake of crushing election results across Britain last week, saying the threshold for a leadership challenge had not been met.A series of cabinet ministers, including David Lammy, the deputy prime minister, rallied round their embattled leader, while more than 110 different backbenchers signed a letter saying it was not the time for a challenge.

“I take responsibility for these election results and I take responsibility for delivering the change we promised,” Starmer told the cabinet meeting.“The past 48 hours have been destabilising for government and that has a real economic cost for our country and for families.The Labour party has a process for challenging a leader and that has not been triggered.“The country expects us to get on with governing.That is what I am doing and what we must do as a cabinet.

”Sources told the Guardian that Starmer did not give cabinet critics time to respond, before moving the conversation on to the Middle East.There was anger within cabinet ranks over what they regarded as Streeting’s attempts to destabilise Starmer, after three of his closest allies – the ministers Jess Phillips, Zubir Ahmed and Alex Davies-Jones – resigned from government and called on the prime minister to go.The health secretary had previously insisted he would not initiate a contest, but would join one if it was already taking place.“Wes has got a brass neck,” one minister said.“Some colleagues are furious with him.

There were evil looks in his direction.”While several sources close to Streeting suggested he did not have the numbers to launch a challenge, one ally said it would be premature to say the health secretary would not be able to do so.“Don’t rule it out yet,” they said.Miatta Fahnbulleh, the first minister to resign on Tuesday, is backing Burnham to replace Starmer.She told the Guardian she wanted the prime minister to set out a timetable for his departure that would allow the Greater Manchester mayor to run.

“Any contest we have had to have our strongest players in it,” she said,“We are not the Tories, we are only going to do this once,We need to have a proper process that allows all candidates to set out their vision for the country,”However, Burnham’s hopes of returning to Westminster were dealt a blow as the Merseyside MP Marie Rimmer, whose seat had been named by key allies for a potential byelection, said she would not stand down and backed Starmer to stay,Starmer was hoping that his second king’s speech, which will be delivered by King Charles on Wednesday, will be a further reset moment for the government that will help unite his deeply divided party.

While he appears to have survived for now, even his most loyal ministers acknowledge that he is unlikely to take Labour into the next election, unless he can dramatically turn round his and the government’s fortunes.Downing Street last night announced four new ministers to replace those who had resigned, including Natalie Fleet to the Home Office, Nesil Caliskan to housing, Catherine Atkinson to justice and Preet Kaur Gill to health.Three more whips were also appointed.In a sign of how close to the brink Starmer may have come, his home secretary, Shabana Mahmood, spent much of the day on resignation watch.Eventually, her spokesperson told reporters: “No [she will not resign].

She is getting on with the job.”Lammy urged MPs trying to get rid of Starmer to back off.“Let’s just step back, take a breath, let’s remember that we have the king’s speech, we are in government to do a job of work,” he said.“It’s been 24 hours now and nobody has come forward to put themselves forward in the processes that exist in the party.No one seems to have the names to stand up against Keir Starmer.

“And for those who are suggesting that he should stand down, they should say which candidate would be better.Let’s get on with the business of running this country and government.”The Guardian understands that Lammy was among four senior cabinet ministers – with Mahmood, defence secretary John Healey and Yvette Cooper, the foreign secretary – who spoke to Starmer on Monday about his future.A Labour leadership election is triggered only if 20% of MPs – in this case 81 – nominate a specific candidate to stand against the leader.The party’s ruling NEC would then make arrangements for a full vote of party members.
