Keir Starmer is facing a political crisis as a growing revolt within the Labour Party has reportedly reached the threshold required to trigger a formal leadership contest, while a serving minister has resigned and called for an “orderly transition” of power. The crisis deepened on Tuesday after Starmer made clear that he would not resign despite mounting pressure from within his own party. Addressing a cabinet meeting at 10 Downing Street, the prime minister said he intended to remain in office and challenged his critics to formally move against him. Starmer told ministers that the country expected Labour to focus on governing rather than internal conflict and stressed that no official leadership contest had yet been triggered. He also warned that the ongoing political turmoil was destabilising the government and carrying a real economic cost for Britain. Rebellion reaches formal challenge threshold According to reports, 81 Labour MPs have now either publicly or privately backed calls for Starmer to step down. Under Labour rules, support from 81 MPs is enough to initiate a formal leadership contest, meaning his opponents now appear to have the numbers required to challenge him. Despite this, no leadership contest has yet been formally launched, largely because the rebellion remains split between rival factions and lacks a single agreed challenger. A Labour minister quoted in British media described the revolt as poorly coordinated, saying the rebellion was accidental in timing and lacked organisation, which has complicated efforts to unite behind a successor. Miatta Fahnbulleh becomes first minister to resign The pressure on Starmer intensified further when Miatta Fahnbulleh became the first serving minister in his government to resign publicly over concerns about his leadership. In her resignation letter, Fahnbulleh said the government had failed to deliver the “vision, pace and ambition” promised to voters and argued that the public no longer believed Starmer could bring the change Labour had pledged. She urged Starmer to “do the right thing for the country and the Party” by setting a timetable for an “orderly transition”, so that a new leadership team could take Labour forward. Although she stopped short of explicitly demanding his immediate resignation, her letter was seen as a major escalation in the internal crisis. Fahnbulleh entered Parliament in 2024 and had been serving as a junior minister in the housing, communities and local government ministry. Before entering politics, she led the New Economics Foundation and was considered a close political ally of Ed Miliband. Her resignation followed the earlier departure of five ministerial aides, underlining the widening discontent within government ranks. Two rival camps shape the revolt The anti-Starmer rebellion is now seen as divided between two major camps, each with different ideas about who should replace him. One faction is centred around Health Secretary Wes Streeting, who is increasingly viewed as the strongest contender from within the current cabinet. Streeting is seen by supporters as a media-savvy figure capable of appealing to a broad national audience and maintaining Labour’s centrist political direction. The second camp is linked to former deputy prime minister Angela Rayner, who remains influential within Labour despite resigning from the cabinet last year. Reports suggest Rayner is backing Andy Burnham as a potential successor and may support a joint political arrangement in which Burnham would become leader and she would return as deputy prime minister. However, Burnham is not currently an MP, which creates a significant obstacle. He would first need to return to Parliament through a by-election before being able to contest the leadership, meaning any immediate challenge under his name would be difficult. Streeting may trigger contest Even though several senior figures are reported to be manoeuvring behind the scenes, no one has yet publicly declared a leadership challenge. Reports suggest Streeting may move first and could formally launch a leadership contest later on Tuesday. If he does, it could mark the beginning of a prolonged struggle for control of the Labour Party. At the same time, senior cabinet members including Yvette Cooper, David Lammy and Ed Miliband are reported to have privately urged Starmer to consider stepping aside, although none has publicly endorsed a challenge. Crushing election losses triggered crisis The immediate trigger for the leadership crisis was Labour’s disastrous performance in Britain’s recent local and devolved elections. The party reportedly lost nearly 1,500 council seats and control of more than 25 local authorities across England. It also suffered severe setbacks in Wales and failed to make meaningful gains in Scotland. In northern England, traditional Labour strongholds swung sharply toward Nigel Farage’s Reform UK, raising alarm that Labour is losing support among working-class voters. At the same time, Labour also lost support on the left, with the Green Party of England and Wales making advances in urban centres and attracting progressive voters who had previously backed Labour. The dual challenge from Reform UK and the Greens has deepened fears among Labour MPs that Starmer’s strategy has alienated both traditional and progressive sections of the party’s voter base. Key tests ahead for Starmer Starmer now faces several critical political tests that could determine whether he survives in office. The upcoming King’s Speech will be closely watched by Labour MPs, many of whom want to see a clear legislative programme capable of restoring confidence after the electoral collapse. Another crucial moment will be the planned UK-EU summit, where Starmer hopes to demonstrate progress in rebuilding Britain’s relationship with Brussels and deliver tangible political achievements, including potential progress on a youth mobility agreement. Some Labour figures believe that if the King’s Speech and the summit fail to shift public opinion, pressure could intensify for Starmer to negotiate a dignified exit after the party’s autumn conference. For now, Starmer remains defiant and has made clear he will not voluntarily step down. But with a serving minister resigning, dozens of MPs openly backing a challenge and rival camps preparing for a succession battle, his grip on power appears increasingly fragile.
