Starmer formally resigns – UK’s seventh Prime Minister in a decade

At around 9:30 a.m. on 22 June, the door of 10 Downing Street slowly opened. Prime Minister Keir Starmer, accompanied by his wife Victoria, stepped out to face the assembled media and formally announced his resignation as leader of the Labour Party, adding that he would step down as Prime Minister once a successor had been chosen. His tenure, which began on 5 July 2024, lasted less than two years.

‘I have heard the answer from my party’

Standing at the lectern outside Number 10, Starmer delivered his resignation speech. He listed his government’s achievements: economic growth exceeding that of comparable countries, wage increases outpacing inflation, an end to fiscal austerity, the fastest reduction in NHS waiting lists in 17 years, the biggest improvements in workers’ and renters’ rights in decades, the largest increase in defence spending since the Cold War, a fall in the number of illegal migrants crossing the Channel in small boats, half a million children lifted out of poverty, and repaired relations with Britain’s European allies.

Yet he ultimately acknowledged a harsh reality: “The question my party has asked is whether I am still the best person to lead Labour into the next general election. I have heard the answer from the parliamentary party, and I accept it fully… I will therefore resign as leader of the Labour Party.” Starmer said he had informed the Royal Household of his decision and asked the party’s National Executive Committee to begin the process for selecting a new leader.

It was plain that he was struggling to contain his emotions – perhaps regret, perhaps a sense of hurt. British media quoted people close to him as saying that he felt “betrayed” by colleagues: he had given himself wholly to the job, only to find that some he regarded as friends had become the force pushing him out. Just a few metres away, on the doorstep of Number 11, senior ministers including the Deputy Prime Minister stood silently. When he finished, they gave him a long round of applause – a scene rich in irony, given that it was precisely the pressure from senior party figures that had forced him to accept his fate.

The final straw

The immediate trigger for Starmer’s resignation was Andy Burnham, the Mayor of Greater Manchester, winning the Markfield by‑election on 19 June with 54.8% of the vote, returning to the House of Commons. That victory not only qualified Burnham to stand for the Labour leadership, but also directly defeated the Reform UK candidate who had been consistently ahead in national opinion polls. Burnham was widely seen as a strong challenger to Starmer’s position.

After Burnham’s win, calls within the party for Starmer to step aside intensified rapidly. Transport Secretary Heidi Alexander urged him to set out a timetable for his departure on the same day, while Home Secretary Yvette Cooper and several other Cabinet members had previously made similar demands. According to Sky News, Foreign Secretary David Lammy also privately asked Starmer to resign over the weekend. The Financial Times reported that by 21 June, as many as 100 Labour MPs had publicly called for Starmer to go – about a quarter of the parliamentary party.

In truth, Starmer’s difficulties had not eased since the local elections in May, when Labour lost nearly 1,500 seats and control of several key councils. Moreover, his appointment of Peter Mandelson – a figure embroiled in the Epstein scandal – as ambassador to the United States had severely damaged his political credibility, especially after further classified documents were released in early 2026. On 11 June, two of the Ministry of Defence’s most senior officials resigned, publicly accusing Starmer of failing to commit sufficient funding to national defence. Former Health Secretary Wes Streeting had also declared in May that Starmer could not lead Labour to victory at the next election and resigned in anger.

A clear timetable for transition

Under the arrangements Starmer announced, nominations for the Labour leadership will open on 9 July and close on 16 July, just before the summer parliamentary recess. Under current party rules, candidates must first secure the nomination of at least 20% of Labour MPs. If more than one candidate comes forward, a full leadership election will be triggered, with the new leader expected to be in place before Parliament resumes in September. Starmer said he would remain in post until his successor was sworn in, to ensure a smooth transition, and promised to give his full support to the new leader.

Burnham emerges as the clear favourite

The overwhelming favourite to succeed Starmer is Andy Burnham. Now 55, Burnham served as Culture Secretary and Health Secretary under Gordon Brown, and after twice failing in leadership bids, left Parliament in 2017 to become Mayor of Greater Manchester, where he has built a strong regional base over nine years. Supporters claim he already has the backing of more than 200 Labour MPs – roughly half the parliamentary party – and former leadership contender Wes Streeting declared on 22 June that he would support Burnham.

Burnham himself signalled his readiness to take over, saying that the transition should be “orderly and responsible” and that the British public expected political stability. Analysts note that Burnham advocates ending “trickle‑down” economics and promoting the re‑industrialisation of northern England. Compared with Starmer’s cautious, technocratic style, Burnham is seen as more adept at clear communication and direct engagement with voters. Stuart Wilks‑Heeg, an elections expert at the University of Liverpool, said Burnham’s large margin in the by‑election was significant and had given him strong political momentum.

Market reaction and deeper challenges

News of Starmer’s resignation caused volatility in financial markets. Sterling fell as much as 0.4% to $1.3181, close to its 2026 low, while the yield on 10‑year government bonds had already climbed to 4.84% on Friday. Economists at Citigroup noted that even if Burnham takes over, he will inherit a fragile fiscal position with little room for manoeuvre.

Analysts point out that Starmer’s resignation means the UK will have had its seventh Prime Minister in the ten years since the Brexit referendum. While the immediate causes have included Brexit disputes, party infighting, scandals and policy failures, the underlying reason is that successive governments have failed to resolve Britain’s deep‑seated economic and social problems. This rapid turnover has created profound political instability and reflects public anger at a succession of governments that have not delivered meaningful improvements in public services or tackled issues such as illegal immigration.

As one correspondent put it on air: “Britain is about to have its seventh Prime Minister in a decade.” The casual tone of that statement only underlined the depth of the country’s political turmoil. Whoever eventually moves into Number 10 will face a host of deep‑seated challenges, including sluggish growth and widening social divisions.
