UK Prime Minister Keir Starmer Expected to Resign After Rival Andy Burnham's Election Win

UK Prime Minister Keir Starmer is expected to announce a resignation timetable as soon as Monday, following a bruising defeat inside his own party. If he steps down, he will be the seventh Prime Minister in a decade — a level of turnover that critics say is damaging Britain's standing in the world, according to AP News.
The crisis was triggered by the Makerfield by-election. On June 19, former Greater Manchester Mayor Andy Burnham won the seat with 55% of 45,510 votes cast — a majority of over 9,000 — and immediately positioned himself as the next Labour leader, according to SFGATE.
Burnham resigned as Mayor of Greater Manchester specifically to run for Parliament and challenge Starmer. He won the Makerfield seat by a landslide. In his victory speech, he called the result a "turning point" for the country, according to AP News. On Monday morning, he is scheduled to be sworn in as a Member of Parliament in the House of Commons.
Over 200 Labour MPs are reportedly ready to sign Burnham's nomination papers if a leadership contest is triggered, according to The Guardian. Around 95 Labour MPs have already publicly called for Starmer to go. Former Home Secretary Alan Johnson summed up the mood bluntly on LBC: "It's over, Keir."
The collapse came fast. On Saturday, Cabinet ministers told Starmer he had until the end of the weekend to set an exit timetable or face being forced out, according to Morningstar. Starmer retreated to Chequers, the Prime Minister's country estate, to "reflect." Health Secretary Wes Streeting was among the high-profile ministers who had already resigned in protest.
Business Secretary Peter Kyle told the BBC on Sunday that Starmer was weighing "political realities" and was aware of the "forces at work" around him, according to The Guardian. Analysts at Ipsos described Starmer as the "least liked prime minister since polling began in 1977" — lower than both Liz Truss and Boris Johnson, according to Forbes.
The roots of the crisis go back to November 26, 2025, when Starmer banned all new North Sea oil and gas licenses — making the UK the largest economy to freeze such exploration. The decision was meant to signal a clean energy commitment. But it backfired badly.
A US-Israel conflict with Iran disrupted global oil supplies, sending energy prices surging. UK households now face a 13% rise in energy bills in July, according to BeInCrypto. That spike — combined with a prolonged cost-of-living crisis — eroded public trust and gave his critics a clear target.
US President Donald Trump jumped into the crisis on Sunday via Truth Social, writing: "Keir Starmer will resign... He failed badly on two very important subjects — IMMIGRATION AND ENERGY (OPEN NORTH SEA OIL!)." The post came before any official announcement from Downing Street, according to Forbes.
The UK press called Trump's comments an "extraordinary foray into UK politics," according to The Hindu. The most likely path forward has Starmer remaining in office until Labour's party conference in late September, allowing Burnham time to build his team for Downing Street, according to The Guardian. Whether Burnham faces a coronation or a contested leadership race remains unclear.
