United Kingdom in June 2026: the most important developments in politics
In the United Kingdom in June 2026, Prime Minister Keir Starmer resigned as prime minister and Labour leader on June 22, the seventh UK prime minister to leave office in ten years. On June 4 Andy Burnham had confirmed he would seek to replace Starmer, and on June 7 Starmer told supporters he would fight any leadership contest. Burnham won the Makerfield by-election on June 19 and was sworn in as an MP within hours of Starmer's resignation. Starmer said he would stay in parliament and promised an orderly transition. The EU postponed a summit with the UK. By month end Burnham was described as prime minister-in-waiting, proposing large-scale decentralisation, including a 'No. 10 North', while other Labour figures weighed leadership bids.
Defence spending was the second theme. Ed Miliband defied Starmer over proposed cuts to fund defence, and on June 11 Defence Secretary John Healey resigned in protest, saying the spending plan fails to fund national security adequately. The armed forces minister also resigned, and Starmer appointed Dan Jarvis as defence secretary. The government said it would publish a Defence Investment Plan before the NATO summit in Ankara.
On foreign policy, Starmer hosted Ukrainian President Volodymyr Zelensky, French President Emmanuel Macron and German Chancellor Friedrich Merz in London on June 7. London, Paris and Berlin backed Zelensky's call for a meeting with Vladimir Putin, and on June 11 British, French and German envoys held talks at the Russian foreign ministry. The UK supplied enriched uranium to Ukraine and imposed new sanctions on Russia. It also joined allies in sanctioning networks financing settler violence in the West Bank, and welcomed the US-Iran agreement.
Other developments included newly released documents on Peter Mandelson, with the top prosecutor saying the investigation could take more than a year. King Charles became the first British monarch to publish his tax payments, a bill of $39.6 million.
