Political Precedents: How Long Do Prime Ministers Survive After Losing Key Advisers?
In the current political climate, one question dominates Westminster corridors: how damaging is the resignation of a prime minister's closest adviser? With Keir Starmer facing intense scrutiny following the departure of his chief of staff Morgan McSweeney yesterday, political observers are examining historical parallels to gauge the potential impact on his premiership.
Historical Comparisons: Prime Minister Tenure After Adviser Departures
Examining recent political history reveals varied timelines for prime ministers who lost key team members:
- Margaret Thatcher remained in office for one year and one month after Alan Walters resigned
- Tony Blair continued as PM for three years and ten months following Alastair Campbell's departure
- Gordon Brown stayed in power for one year and one month after Damian McBride's resignation
- Theresa May remained as prime minister for two years and one and a half months after Nick Timothy and Fiona Hill left
- Boris Johnson continued for one year and ten months after Dominic Cummings resigned, and seven months following Munira Mirza's departure
These examples demonstrate that while adviser resignations create significant turbulence, they don't necessarily precipitate immediate prime ministerial exits.
The McSweeney Resignation: Mixed Reactions and Historical Parallels
The departure of Morgan McSweeney has generated conflicting responses within Labour ranks. While some MPs welcome his exit, others credit him with securing their parliamentary seats and express concern about how Starmer will manage without his strategic guidance.
Comparisons with Dominic Cummings emerge due to both advisers being credited with election victories - Cummings with Johnson's 2019 win and McSweeney with Labour's 2024 landslide. However, election expert Professor Jane Green of the British Election Study recently noted that "the major factors that contributed to the unique seats-votes outcome were outside Labour's direct control", challenging the narrative of McSweeney's decisive influence.
Some analysts see closer parallels with Theresa May's advisers Nick Timothy and Fiona Hill, who played crucial roles in her becoming prime minister, similar to McSweeney's instrumental guidance in Starmer's Labour leadership victory. However, Timothy and Hill exercised more dominant control in Number Ten and were forced out after an election-losing manifesto, whereas McSweeney achieved the opposite electoral outcome.
Today's Political Landscape: Damage Control and Party Management
As the crisis unfolds, Keir Starmer faces the immediate challenge of reasserting control over his party. The prime minister is scheduled to address Labour MPs this evening in a private Parliamentary Labour Party meeting, where he'll need to demonstrate leadership stability.
Former Labour home secretary Jacqui Smith, now a peer and skills minister, has been defending Starmer's position in media appearances, stating on Times Radio that the prime minister deserves credit for "taking responsibility" for the Peter Mandelson appointment. She emphasised that "the prime minister is taking responsibility. He took responsibility for the decision that was made about Peter Mandelson", while noting that Mandelson's actions regarding Jeffrey Epstein had let down the party, government, and country.
Labour First, the right-leaning faction supporting Starmer, has been circulating talking points to sympathetic backbenchers ahead of tonight's PLP meeting. These include highlighting how the PM "accepts his mistakes and apologises" compared to Conservative leaders, and emphasising the government's delivery on "many areas of incremental change".
Today's Political Agenda: Key Events to Watch
The political focus remains firmly on this developing crisis, with several significant events scheduled:
- Morning: Kemi Badenoch conducts a visit in Surrey
- 11:30am: Downing Street holds its regular lobby briefing
- 2:30pm: Home Secretary Shabana Mahmood faces Commons questions
- 3:00pm: Reform UK leader Nigel Farage delivers a speech in Birmingham
- 6:00pm: Keir Starmer addresses Labour MPs at the private PLP meeting in Westminster
While historical precedent suggests that even damaging resignations like McSweeney's don't necessarily make a prime minister's departure imminent, the coming days will reveal whether Starmer can successfully navigate this political storm and maintain his authority within both his party and the government.
