London — Keir Starmer is battling the most serious crisis of his premiership after Labour’s heavy local and devolved election losses triggered open calls inside the party for him to resign and raised the prospect of a formal leadership challenge.The Prime Minister has insisted he will not step aside, telling allies that his government remains a long-term project and that leaving now would plunge the country into political instability. His stance has not halted the backlash. Labour MPs, councillors and union figures have warned that the party’s electoral coalition is fracturing less than two years after its general election victory.
The May 7 elections produced Labour’s worst local performance in more than three decades. The party lost roughly 1,500 council seats and control of dozens of authorities, while Reform UK advanced sharply across former Labour strongholds. The Conservatives also suffered losses, but Labour’s retreat in working-class towns, parts of London, Wales and northern England has alarmed MPs who fear the party is being squeezed from several directions at once.
Catherine West, the MP for Hornsey and Friern Barnet and a former Foreign Office minister, has become the most visible internal critic. She has said she would stand as a challenger unless a senior cabinet figure moved against Starmer. Under Labour rules, a challenger needs nominations from 20 per cent of Labour MPs, equivalent to 81 MPs in the current parliamentary party. That threshold remains difficult to reach, but the threat has turned private discontent into a public test of Starmer’s authority.
Around 30 to 40 Labour MPs have publicly urged Starmer to resign, set out a departure timetable or change course. Several others are understood to be waiting to see whether cabinet ministers break ranks. The cabinet has so far held its line. Education Secretary Bridget Phillipson said a leadership challenge would be the wrong response to voters’ anger, while other ministers have argued that Labour must show discipline and shift policy rather than descend into a prolonged internal contest.
The scale of the losses has sharpened questions over the government’s economic and political strategy. Labour came to power promising stability, higher growth and stronger public services after years of Conservative rule. Voters have instead encountered stubborn living-cost pressures, frustration over NHS waiting lists, disputes over welfare and pensioner support, and unease over migration. Starmer’s cautious governing style, once presented as a strength, is now being criticised by some Labour MPs as too managerial and too slow to connect with the public mood.
Reform UK was the main beneficiary of Labour’s troubles in many English councils, gaining ground in areas that had already shown signs of volatility since Brexit. Nigel Farage has presented the results as evidence that British politics has moved beyond the old two-party contest. The Greens also made gains in urban and progressive areas, while Plaid Cymru’s surge in Wales underlined the depth of Labour’s difficulties in territory it once treated as politically secure.
Wales delivered one of the starkest warnings. Labour, which had dominated Welsh politics for a century, was pushed into a distant position behind Plaid Cymru and Reform UK in the Senedd election. The outcome reflected anger over public services, economic stagnation and voter fatigue with Labour administrations at both Cardiff Bay and Westminster. Scotland also offered little relief, with Labour failing to make the breakthrough it had hoped for against the SNP and other rivals.
Starmer has responded by promising a reset. He is expected to set out what aides describe as a fresh direction, with greater emphasis on living standards, public service delivery and closer ties with the European Union. He has also brought former prime minister Gordon Brown and former deputy Labour leader Harriet Harman into advisory roles, a move intended to reassure MPs that the leadership recognises the seriousness of the defeat.
The challenge for Starmer is that a reset may not satisfy MPs who believe the problem lies less in presentation than in political identity. Critics argue that Labour has alienated pensioners, public-sector workers, younger progressive voters and parts of its traditional base without building a convincing new coalition. Union pressure has intensified, with warnings that Labour risks losing its working-class foundation unless it offers clearer gains on wages, jobs and services.
