UK Prime Minister Keir Starmer resigned today. He stepped down as both party leader and head of government after Labour MPs staged an open revolt against his leadership.

Trump had predicted the move just one day earlier. In a Truth Social post Saturday, he said Starmer had failed badly on energy and immigration. He then demanded the UK open North Sea oil.

Starmer Resigns After Labour Party Revolt

Starmer’s fall ends a tenure that began with a historic Labour landslide in 2024. Since then, the party lost more than 1,000 council seats in May’s local elections. Around 100 Labour MPs formally wrote to Starmer, asking him to step down.

Welfare reform proposals added to the internal friction. So did the appointment of Peter Mandelson as US ambassador. His links to the late Jeffrey Epstein drew sharp criticism from MPs and deepened divisions inside the cabinet.

Starmer confirmed the news through his personal X account Monday morning. He said he would set out a departure timetable and begin a formal Labour leadership contest.

North Sea Ban Seen as Keir Starmer’s Biggest Miscalculation

In November 2025, the UK banned all new North Sea oil and gas exploration licenses. That made it the largest economy to take that step. Supporters framed the move as a clean energy commitment. However, critics warned it left Britain exposed to any commodity shock.

The Iran conflict that began in early 2026 sent Brent crude from around $73 a barrel to nearly $114. Ofgem then confirmed a 13% rise in household energy bills from July. The average annual bill climbed from £1,641 to £1,862.

Oxford’s Smith School found that full North Sea output would have cut bills by only £16 to £82 annually. In other words, oil trades at global prices regardless of origin.

Trump had flagged the same vulnerabilities in May 2026, citing failures on energy and immigration. His June 21 Truth Social post removed any ambiguity about Starmer’s political fate.

What Comes Next for UK Leadership

Meanwhile, Andy Burnham won the Makerfield by-election last week with 54.8% of the vote. He is the clear frontrunner to replace Starmer as Labour leader. Burnham openly backs digital assets and told Web3 founders he wants Manchester to lead the crypto sector.

His stance clashes with current Labour party policy. Starmer’s government placed a moratorium on crypto donations to political parties in March 2026. UK crypto voters will closely watch how Burnham shapes that policy if he wins the leadership race.

Prediction markets have moved sharply in Burnham’s favor. The US-Iran oil shock that accelerated Starmer’s resignation now poses the first major fiscal test for whoever leads Labour next.
