U.K. Prime Minister Keir Starmer announced on Monday that he will step down as Labour leader and prime minister, ending months of political turbulence and triggering a leadership contest to determine his successor.
The decision follows mounting pressure after Labour suffered significant losses in May's local elections and faced growing opposition from within its own ranks over Starmer's leadership and policy direction.
The announcement comes less than two years after Starmer led Labour to a landslide victory in the 2024 general election, securing one of the party's largest parliamentary majorities in modern history.
Speaking outside 10 Downing Street shortly after 9:30 a.m. in London, Starmer said he would remain in office until the leadership transition is completed to ensure an orderly transfer of power.
The resignation follows a decisive victory by former Greater Manchester mayor Andy Burnham in a special election on June 18, a result that positioned him as a leading contender to succeed Starmer and potentially become Britain's next prime minister.
In an emotional speech, Starmer described entering Downing Street as the "proudest moment of my life." He said his government had restored Britain's international standing, attracted investment and strengthened workers' rights during his tenure.
However, he acknowledged growing concerns within Labour over whether he remained the right person to lead the party into the next general election.
"I have heard the answer from my parliamentary party. I accept that answer with good grace. I will resign as leader of the Labour Party," Starmer said.
Financial markets reacted cautiously to the news. The pound fell 0.19% against the U.S. dollar to $1.3207, while yields on 10-year U.K. government bonds, known as gilts, remained largely unchanged at 4.8452%.
Gilt yields had already risen on Friday following Burnham's by-election victory. Burnham has since attempted to reassure investors, distancing himself from earlier remarks suggesting that Britain was "in hock to the bond markets."
Kallum Pickering, chief economist at Peel Hunt, said Britain continues to face high borrowing and debt levels but is not a fiscal outlier compared with other G7 economies.
He noted that under Starmer's leadership, Britain had expanded its global engagement through new trade agreements and achieved 1.5% real GDP growth.
However, Pickering also pointed out that Britain still faces the highest borrowing costs and among the highest inflation rates in the G7, problems that have persisted for much of the past decade.
"This is what the market is concerned about," Pickering told CNBC's Squawk Box Europe shortly after Starmer's announcement. "Investors now have to price in what a Burnham premiership would look like."
Starmer and Finance Minister Rachel Reeves had increasingly struggled to contain internal divisions over fiscal policy. Welfare reforms and the appointment of Peter Mandelson, an associate of convicted sex offender Jeffrey Epstein, as U.S. ambassador further strained relations within the party.
An Ipsos poll published on Friday found that 52% of Britons believed Starmer should resign as prime minister, up five percentage points from May, while only 35% thought he should remain in office.
Starmer's resignation comes almost a decade after Britain voted to leave the European Union. His successor will become the country's seventh leader during that period, highlighting the prolonged political instability that has continued long after Brexit was formally completed.
David Cameron resigned after losing the 2016 Brexit referendum. Theresa May succeeded him but stepped down after failing to secure parliamentary support for her Brexit plans. Boris Johnson then took office but resigned in 2022 following a wave of ministerial resignations linked to his handling of misconduct allegations involving senior Conservative lawmaker Chris Pincher.
Liz Truss replaced Johnson but resigned after just 50 days when her unfunded tax-cutting "mini-budget" triggered turmoil in financial markets, sending gilt yields soaring and weakening the pound. Rishi Sunak subsequently took over, confronting high inflation and a cost-of-living crisis exacerbated by the war in Ukraine.
Starmer later defeated Sunak in the July 2024 general election, returning Labour to power after 14 years in opposition. Despite winning a commanding 174-seat majority, his government gradually lost momentum amid declining approval ratings, internal party disputes and growing public frustration over the pace of economic improvement and cost-of-living relief.
Monday's announcement now formally opens the process of selecting Labour's next leader.
Burnham received an endorsement from former health secretary Wes Streeting, who had previously been considered a potential challenger.
In a post on X, Burnham paid tribute to Starmer and said the transition process should be handled responsibly.
"It is important that this process is conducted in an orderly and responsible way. I will put myself forward as part of this process," Burnham wrote.
Starmer said he would remain prime minister until Labour formally selects a new leader, a process that could conclude within weeks if Burnham faces no opposition.
