Who is Keir Starmer without Morgan McSweeney?

Following a “tsunami of pressure” from Labour MPs, Keir Starmer has lost his right-hand man and the architect of his rise to become prime minister, said Anne McElvoy in The i Paper.

“Outraged” by the appointment of Peter Mandelson as US ambassador despite his known links with Jeffrey Epstein, as well as a broader “autocratic culture in No. 10”, the MPs’ ire was directed, in part, at Downing Street chief of staff Morgan McSweeney.

Following his resignation yesterday, McSweeney has been replaced by his former deputies, Vidhya Alakeson and Jill Cuthbertson, on an interim basis.

“In the end, the PM had little option,” said Sky News’ political editor Beth Rigby. Starmer has “lost the backbone of his operation” but many MPs are now calling for his head.

What did the commentators say?

Starmer will be “disorientated” after McSweeney’s departure, said Patrick Maguire in The Times. Arguably, the Irishman “remade” the Labour Party, leading the charge against the confrontation-shy “Librarian Labour” stereotype, and his departure has left Starmer “adrift”. It is unclear what a post-McSweeney Labour Party stands for, apart from an “unreconstructed, middle-of-the-road progressivism” embodied by Starmer.

McSweeney’s resignation could offer a “new beginning” for the PM and his government, said Polly Toynbee in The Guardian. If the party wants to change public opinion, and recover from a series of major policy U-turns, Starmer had “better grab it”.

The former chief of staff had become the “punch bag for everything that has gone wrong” for Labour since the 2024 election. “Now it can change tack.” The PM’s change in personnel could “signal” a moment of “new purpose” for his struggling government. One thing is for sure: “there are no more excuses”.

No. 10 is in “full-blown survival mode”, said Rigby on Sky News. Starmer will be clinging to the hope that McSweeney’s departure will “go some way to satisfying some of his MPs who were demanding a reset”. Ultimately, however, “it might only serve to weaken him further now that his key ally and fixer has gone”. The operation is in “freefall” and if history is to be believed, “it’s near impossible to stabilise” in this situation.

Labour’s crisis “won’t be fixed by a sacrificial resignation”, said Neal Lawson in The New Statesman. Starmer is the face of a “deep-rooted and systemic crisis” of identity that has “dominated” Labour for decades. “In every sense – morally, politically and electorally – Labour has been brought to its knees.” If Starmer wants to drag the party towards success, he needs a “total reset of the Labour project”.

“What could a Starmer government possibly achieve now?” said Isabel Hardman in The Spectator. McSweeney’s departure will buy a little “extra time” for the PM, “like a patient bargaining for expensive life-extending drugs”. However, that “doesn’t change the diagnosis: this is a government that no longer works”.

What next?

Downing Street’s communications director, Tim Allan, stepped down from his role this morning, saying it would allow a “new No. 10 team to be built”. So the “second high-profile exit” from Starmer’s “crisis-hit team in less than 24 hours” leaves him looking for his fifth comms chief since he took office, said Politico.

Just six weeks ago, McSweeney told a group of special advisers that the government had “turned a corner”: indeed, it was “down a blind alley to oblivion”, said Maguire in The Times. Fast forward to today and it is “likely that Starmer will leave office – soon – having changed neither” Labour nor Britain.

If it was right for McSweeney to resign for recommending the appointment of Mandelson as US ambassador, then “why is it not also a resigning matter to act on that advice?” said John Rentoul in The Independent. “Advisers only advise; ministers decide.” Starmer is “running out of things to throw overboard to try to keep himself afloat”.

Frankly, sacrificing McSweeney “won’t work” and only “desperate measures” are now left. Starmer could follow Tony Blair’s “gambit” in 2006, when, undermining a leadership coup, he announced that he would be stepping down within a year to “buy himself” time.

If Labour comes third in the Gorton and Denton by-election on 26 February, “as seems likely”, this could “trigger the final moves”. With his “penultimate line of defence” breached, “we enter the endgame of Starmer’s premiership”.
