British Prime Minister Keir Starmer is facing the most significant crisis of his leadership since coming to power in July 2024, as calls for his resignation mount from within his own Labour Party. In a tense Cabinet meeting on May 12, 2026, Starmer told his ministers unequivocally that he would not step down, despite a growing rebellion among Labour MPs and a wave of resignations from his government. The political drama has sent shockwaves through Westminster and rattled financial markets, raising questions about the future direction of the UK’s government.
Starmer’s defiance comes in the wake of Labour’s disastrous performance in local elections held on May 7, 2026. According to Reuters and BBC, the party lost more than 1,400 seats and relinquished power in Wales, with voters turning to the anti-immigrant Reform UK, the Green Party, and nationalist parties in Scotland and Wales. The result has been described by some Labour insiders as “catastrophic,” and it has triggered a wave of internal dissent not seen since the party’s time in opposition.
By midday on May 12, at least 89 Labour MPs—nearly a fifth of the parliamentary party—had publicly called for Starmer to resign or to set a timetable for his departure, as reported by The Telegraph and BBC. The pressure was further intensified by the resignation of several junior ministers. Miatta Fahnbulleh, the Minister for Devolution, Faith and Communities, was the first to step down, minutes before the Cabinet meeting began. In her resignation letter, she urged Starmer “to do the right thing for the country” and set out a timetable for his exit, stating, “Nor have we governed as a Labour Party clear about our values and strong in our convictions.”
She was quickly followed by Safeguarding Minister Jess Phillips, who criticized Starmer for “rarely making an argument,” and Alex Davies-Jones, Minister for Victims & Violence Against Women and Girls, who called on the prime minister to step down after what she termed “catastrophic” electoral defeats. In her letter, Davies-Jones wrote, “I implore you to act in the country’s interest and set out a timetable for your departure. I know you to be a good and honest man. But in my heart are my constituents, the victims I have had the honour of working with every day.” Later that day, Zubir Ahmed, a Health minister and close ally of Health Secretary Wes Streeting, also resigned, stating, “It is clear from recent days, that the public across the UK has now irretrievably lost confidence in you as Prime Minister.”
Inside the Cabinet, divisions were apparent. According to The Telegraph and other UK news outlets, at least six senior ministers—including Foreign Secretary Yvette Cooper, Home Secretary Shabana Mahmood, Defence Secretary John Healey, Energy Secretary Ed Miliband, Culture Secretary Lisa Nandy, and Health Secretary Wes Streeting—were reported to have urged Starmer to oversee a transition of power. Mahmood is understood to have told Starmer directly that he should step aside, reflecting the depth of concern among the party’s upper ranks.
Despite these internal challenges, some Cabinet ministers rallied behind Starmer. Secretary of State for Work and Pensions Pat McFadden told reporters after the meeting that “no one challenged” the prime minister during the session. Technology Secretary Liz Kendall and Labour Party Chairwoman Anna Turley both declared their “full support” for Starmer, with Kendall emphasizing, “There’s a process to challenge the leader. No one has made that challenge.” Business Secretary Peter Kyle echoed this sentiment, saying, “We’re working hard on the big issues that are facing the country, and Keir is showing steadfast leadership.”
Under Labour Party rules, a leadership contest can only be triggered if a challenger secures the backing of at least 20% of Labour MPs—currently 81 members. As of May 12, no formal challenge had been launched, though the threshold was within reach given the number of MPs calling for Starmer’s resignation. Starmer reminded his colleagues, “The country expects us to get on with governing. The past 48 hours have been destabilizing for government and that has a real economic cost for our country and for families.”
The economic fallout was immediate and severe. On May 12, the pound dropped 0.7% against the dollar and 0.4% against the euro. The FTSE 100 slid by 0.5%, and government bond yields soared to their highest levels in nearly three decades. The yield on 30-year bonds reached 5.797%, while the 10-year rate hit 5.116%. As Kathleen Brooks, research director at broker XTB, told Reuters, “The bond market is reacting not only to Starmer’s potential departure but also to who his successor could be and to the prospect of a drawn-out leadership battle that leads to more fiscal promises that the UK cannot afford.”
Potential challengers to Starmer are already being discussed in Westminster. Health Secretary Wes Streeting, whose allies have been among the first to resign, is widely seen as a frontrunner should a contest be triggered. Other names in the frame include former Deputy Prime Minister Angela Rayner and Greater Manchester Mayor Andy Burnham. However, Rayner’s candidacy is complicated by an ongoing tax investigation, while Burnham is not currently an MP and would need to win a by-election to stand. As noted by BBC, Burnham was previously blocked from standing in a by-election by Labour’s National Executive Committee, a move Rayner later described as a “mistake.”
Starmer has attempted to regain momentum with a speech on May 11, in which he took responsibility for the “very tough” election results but warned that Labour would “never be forgiven for inflicting” the “chaos of constantly changing leaders,” as seen under the Conservatives, on the country again. He positioned Labour as “a mainstream party of power, not protest,” and criticized both Reform UK and the Greens for “preying on despair that they exploit and amplify.”
Yet, the challenges facing Starmer are significant. His government, which ended 14 years of Conservative rule in a landslide less than two years ago, now finds itself beset by internal fractures, policy missteps—including the controversial appointment of Peter Mandelson as ambassador to Washington—and a faltering economy. The decision to cut the winter fuel allowance during a cost-of-living crisis and Labour’s policy on Gaza have also alienated key voter blocs, fueling the rise of both Reform UK and the Greens.
With the next general election not required until 2029, Starmer’s fate may be determined by whether his party can unite behind his leadership or whether the mounting pressure will force a leadership contest. For now, the prime minister is digging in, insisting that “the country expects us to get on with governing.” But as the events of the past week have shown, the ground beneath his feet is far from stable.
The coming days will reveal whether Starmer’s gamble to stay the course pays off—or whether Labour’s internal divisions will usher in yet another chapter of political upheaval in the UK.
