UK Prime Minister Keir Starmer Expected To Resign On Monday: Report

Keir Starmer’s premiership appears to have entered its final act. Just over a week after Andy Burnham stormed back into Parliament with a crushing by-election win, the Prime Minister is – according to senior Labour figures cited by The Observer – preparing to set out a timetable for his own departure, with a “clear statement” possible as early as Monday.

It would be a remarkable collapse. Starmer led Labour to a landslide less than two years ago. He now looks unable to command the confidence of his own benches for much longer, with cabinet ministers, union leaders and donors reportedly among those who have been involved in the conversations about his future.

Burnham, the outgoing Greater Manchester mayor, did not just win Makerfield – he buried it. Official figures show him taking 24,927 votes, 54.8% of the total, beating Reform UK’s Rob Kenyon by a 9,231-vote margin in a seat where Nigel Farage’s party had been threatening to turn Labour’s crisis into a rout. The result gives Burnham the Commons seat he needs, clears his path to a leadership challenge, and leaves Starmer’s position looking terminal.

Also, Starmer’s former Chief of Staff – Morgan McSweeney – was the sacrificial lamb in the Mandelson scandal (recall that Starmer appointed Jeffery Epstein pal Peter Mandelson as the UK’s ambassador to the US). McSweeney also targeted Zerohedge, The Federalist and Breitbart in a clandestine campaign against alternative-media outlets. He resigned in February, two weeks before Mandelson was arrested on suspicion of passing insider info to Jeffrey Epstein in 2009, when he was serving as Business Secretary.

Markets Eye The Monday Open

The political risk did not go unnoticed by bond traders. UK 10-year gilt yields climbed to 4.84% on Friday, up roughly 0.09 percentage points on the session, as markets weighed Burnham’s victory, domestic political uncertainty, and the possible fiscal implications of a future leadership bid.

With markets shut over the weekend, the next read comes at Monday’s open, and any Starmer statement setting out an exit timetable will land straight into it.

Burnham is due to be sworn in as an MP on Monday and to meet Starmer early in the week, with a cabinet meeting scheduled for Tuesday. Senior Labour figures expect a “deliberate slow march in good order” – most likely a September handover timed to the party conference – rather than an immediate vacuum.

According to the report, Burnham’s supporters claim he has secured backing from more than 201 Labour MPs if Starmer refuses to step down voluntarily. The Observer framed that as a critical number because it would represent more than half the Parliamentary Labour party and would make it increasingly difficult for Starmer to argue that he still commands the confidence of his own side.

A formal challenge requires far fewer names. Under Labour’s rules, any challenger needs nominations from 20% of Labour MPs – currently 81 – plus the required support from local parties and affiliates. On every count, the door is open.

Starmer Digging In?

For now, at least in public, Starmer is not going quietly. On Friday he congratulated Burnham on X – framing the result as a win for “Labour’s campaign of hope and optimism over division and hate” – while insisting he would stand in any leadership contest and still had “more to do.”

Congratulations, @AndyBurnhamGM, Labour’s new MP for Makerfield.

Voters chose Labour’s campaign of hope and optimism over division and hate.

By Saturday the mood music had shifted. The Observer reports that Starmer was spending the weekend at Chequers with his wife, Victoria, weighing his future after a round of conversations with cabinet ministers, advisers, union bosses and donors.

One Labour peer close to the Prime Minister told the paper that Starmer would not “walk away” from No. 10 creating a vacuum, but would instead “arrange a deliberate slow march in good order, as a matter of duty and dignity.” Another Labour grandee said the Prime Minister now appeared “resigned” to stepping down after coming “hard against the reality that the support isn’t there.”

The establishment knives are out. Lord Falconer – Starmer’s own former shadow attorney general – told the BBC that the Prime Minister had “absolutely no authority left because everybody assumes Andy Burnham is about to challenge for the leadership and everybody assumes he’s going to win.”

Former Health Secretary Wes Streeting, who remains the obvious alternative pole of opposition inside the party, publicly hailed Burnham’s result even as allies insisted he still intends to stand in any contest.

Huge congratulations to @AndyBurnhamGM on an astonishing victory in Makerfield, where Labour lost badly only weeks ago.

It gives us all hope that Labour can still win, but Andy’s campaign is proof that to do so we need to change.

Enormous thanks to everyone involved.

Even the money is moving. Unite general secretary Sharon Graham said “obviously Starmer needs to go,” calling for an orderly transition on a clear timetable and a conversation about Labour’s policy priorities.

Streeting’s allies, meanwhile, are still talking as though the fight is alive. The Observer reported he has taken out a contract on an office for 40 members of staff as campaign headquarters and has received two £50,000 donations from Fran Perrin, one of Labour’s most generous supporters. But some senior Labour figures now believe Streeting may ultimately do a deal with Burnham rather than stand in the way of the momentum.

“A Final Chance To Change”

Burnham’s victory speech left no doubt about the scale of his ambition, even if he stopped short of formally launching the challenge. “Tonight could – just could – be the turning point,” he told supporters, warning Labour it had a “final chance to change” with “no second chance.”

There was also some weirdness: animal-rights campaigner Robert Pownall, who ran as an independent, and Count Binface, the bin-headed “intergalactic space warrior,” who took 95 votes.

“I swear I’ll move to Makerfield if I win.”

Mandlelson & Epstein

Burnham’s win was the trigger, but the charge had been laid months earlier. The slow detonation of Starmer’s authority traces back to his decision, in December 2024, to hand the plum Washington ambassadorship to Peter Mandelson despite Mandelson’s long-public friendship with the late convicted sex offender Jeffrey Epstein.

Mandelson was sacked as ambassador in September 2025 after released material appeared to show a closer relationship with Epstein than had been acknowledged at the time of appointment. He was later arrested on suspicion of misconduct in public office over allegations that sensitive government information had been passed to Epstein during the 2008-2010 financial crisis. Mandelson has denied wrongdoing, has not been charged, and the police investigation is ongoing.

Starmer claimed Mandelson had lied throughout the appointment process – however it later emerged that he knew full well of the friendship.

Wow.

The Mandelson files are up.

They prove Starmer WAS advised and warned about Mandelson’s appalling friendship with Epstein.

Starmer appointed him anyway.

Starmer lied.

By then the damage was structural: his chief of staff Morgan McSweeney had resigned over the affair, a top Foreign Office mandarin was on the way out, and the government had spent months bleeding credibility through document dumps, a vetting row, sleaze-inquiry pressure and a steady drip of resignations.

No. 10 is still batting the resignation talk away as “speculation,” and Starmer’s team insists he will fight any challenge. On Friday, the Prime Minister told staff the party had to “pull together” and “take the fight” to Reform.

But the shape of the problem is brutal: Burnham has the seat, his allies claim the numbers, cabinet ministers are turning, the unions are turning, and Reform UK remains the threat Labour MPs increasingly believe only Burnham can blunt.

If Starmer steps to a podium on Monday and sets out an exit timetable, it will cap an extraordinary fall – from landslide to forced retreat in under two years – and crack open the door for the man they call the “King of the North” to walk through it.

Maybe if Starmer had addressed unchecked migration, England’s woke police, or the rape gangs his CoS tried to get us demonetized for reporting on…
