Keir Starmer, the UK Prime Minister and Labour Party leader, is facing intense scrutiny and growing calls to resign following a series of political setbacks, scandals, and disastrous election results in 2026. Less than two years after leading Labour to a landslide victory in 2024, Starmer’s approval ratings have plummeted, and dissatisfaction within his own party is mounting.
TodayWhy explores the main reasons behind the pressure on Starmer to step down, from local election humiliations to high-profile controversies.
1. Crushing Defeat in Local and Regional Elections
One of the biggest triggers for the current crisis was Labour’s heavy losses in the May 2026 local elections across England, along with poor results in Wales and Scotland.
- Labour lost control of more than 25 English councils and over 1,100 seats.
- Nigel Farage’s Reform UK made significant gains, particularly in the Midlands and North.
- Senior Labour figures, including dozens of MPs, urged Starmer to announce a departure timeline within the year.
These results were widely viewed as a referendum on Starmer’s leadership. Many voters expressed frustration over the pace of change, rising living costs, immigration, and perceived broken promises.
Despite the backlash, Starmer has insisted he will not resign, stating he will not “plunge the country into chaos” and plans to “rebuild” the party.
2. The Peter Mandelson Scandal and Security Vetting Controversy
A persistent and damaging issue has been the appointment of Peter Mandelson as UK Ambassador to the United States. New revelations in 2026 intensified calls for Starmer’s resignation.
Key elements of the scandal include:
- Mandelson reportedly failed security vetting but was appointed anyway, with the Foreign Office allegedly overruling concerns.
- Links between Mandelson and the late Jeffrey Epstein resurfaced, adding to the controversy.
- Starmer has denied deliberately misleading Parliament, claiming he was unaware of key details. Critics argue this points to poor judgment or a lack of control over his government.
The affair led to multiple resignations in Starmer’s inner circle and accusations that he threw civil servants under the bus to protect himself. Several Labour peers and MPs described the situation as unsustainable, with one stating Starmer “cannot conceivably continue as a credible Prime Minister.”
3. Plummeting Approval Ratings and Loss of Public Trust
Starmer’s personal popularity has collapsed dramatically since taking office:
- Net approval ratings have reached deeply negative territory (around -45 or worse in some polls).
- Satisfaction ratings as low as 18-22% in early 2026.
Voters cite slow progress on key issues like the NHS, economy, and immigration. Many feel the government lacks direction despite the large parliamentary majority won in 2024. U-turns, internal chaos, and a sense of “crisis management” rather than bold leadership have further eroded confidence.
4. Internal Labour Party Rebellion
Pressure is not just coming from opposition parties like the Conservatives and Reform UK. A growing number of Labour MPs (reports suggest 35–70+) are publicly or privately calling for Starmer to go or set a clear exit plan.
- Some backbenchers are gathering support for a leadership challenge or timetable.
- Speculation about potential successors, such as Andy Burnham, has increased.
- Resignations and high-profile criticism from within the party signal deep divisions.
5. Broader Pattern of Perceived Misjudgments
Critics argue the Mandelson affair is not an isolated incident but part of a pattern that includes:
- Multiple U-turns on policy.
- Handling of donor “freebies” controversies.
- Perceived weakness on immigration and economic delivery.
- High staff turnover in No. 10 Downing Street.
This has damaged Starmer’s brand as a competent, steady leader who promised to restore stability after years of Conservative turmoil.
Can Keir Starmer Survive?
As of May 2026, Starmer is defiant. He has taken responsibility for the poor election results while highlighting achievements in areas like NHS waiting times and child poverty reduction. He has also announced initiatives such as nationalizing parts of British Steel and creating work opportunities for young people.
However, with local election losses, ongoing scandals, terrible polling, and a restive parliamentary party, the pressure is unlikely to ease soon. Many analysts see 2026 as a make-or-break year for his premiership.
The coming months will be critical. If Labour cannot stem the rise of Reform UK or deliver tangible improvements felt by voters, the calls for Starmer to resign may become irresistible.
Who Could Replace Starmer?
If Starmer were to resign or be removed, the most frequently discussed successors include:
- Wes Streeting (Health Secretary): Seen as a centrist moderniser; several of his allies have been among those calling for Starmer to go.
- Andy Burnham (Mayor of Greater Manchester): Widely popular and seen as having strong electoral appeal, particularly in the north of England. However, he would need to win a parliamentary seat to be eligible.
- Angela Rayner: The former deputy leader remains influential and has been critical of Starmer’s direction, though she has not formally entered the race.
Any leadership contest would need to follow Labour’s internal rules, requiring a threshold of MP nominations before the membership gets a vote.
What Happens Next?
As of May 2026, the political situation remains fluid. Key things to watch:
- The King’s Speech (scheduled for Wednesday, May 13): Starmer is hoping to use this as a legislative “reset,” laying out a bold new programme of government.
- Whether the number of MPs calling for his departure reaches 81: If it does, a formal leadership challenge becomes mathematically possible.
- Andy Burnham’s next move: If the Manchester mayor signals ambition for the top job and finds a route back to Westminster, the dynamics could shift rapidly.
- Ongoing fallout from the Mandelson inquiry: Further documents and evidence are expected, which could reignite or escalate the parliamentary crisis.
Conclusion
Keir Starmer is under pressure to resign due to a perfect storm of crises: a damaging scandal over the appointment of a security-failed, Epstein-linked ambassador; historic local election losses to Reform UK; a struggling economy; a backlash over welfare cuts; and a growing rebellion among Labour MPs who fear the party’s direction is unsustainable.
While Starmer has so far refused to step down — insisting he will not “plunge the country into chaos” — the voices demanding change within his own party are growing louder by the day. Whether his attempted reset will be enough to stabilise his position, or whether Labour will move to replace him before the next general election, remains one of the defining political questions of 2026.
