LONDON — British Prime Minister Keir Starmer may announce a timeline for leaving office as soon as Monday, potentially setting the stage for an orderly handover of power to rival Andy Burnham and making him the United Kingdom’s seventh leader in a single decade.
Not even two years after Starmer led Labour to a sweeping election victory — one that was supposed to bring stability to Britain’s turbulent political scene — a source close to him said the prime minister spent the weekend weighing his options: either step aside voluntarily or fight to keep his job in a formal party leadership contest.
“Keir likes to think about things,” the source said, speaking on condition of anonymity.
The pressure on Starmer has been mounting for months, but it intensified sharply on Friday when Burnham, who currently serves as the mayor of Greater Manchester, won a parliamentary by-election and returned to Westminster. His victory came at the expense of a candidate from Nigel Farage’s Reform UK party, which has topped national opinion polls for over a year.
That win energized Labour lawmakers who believe Burnham — a veteran politician widely praised for his ability to communicate — could reverse the party’s declining fortunes. Starmer’s personal approval ratings have fallen to the lowest level recorded for any British prime minister.
However, a leadership change carries its own risks. Burnham has spoken broadly about the need for sweeping national change and reducing the cost of living, but has not laid out detailed positions on foreign policy, economic strategy, or defense spending.
Much like Starmer, Burnham could find his hands tied by bond market investors who strongly resist any increase in government borrowing. He would also face a frustrated public that feels the country’s core systems are failing them.
Britain currently carries the heaviest borrowing costs among the Group of Seven wealthy nations, a situation driven by high debt levels, years of sluggish economic growth, difficulties in cutting public spending, and growing demands for investment in areas such as defense.
Investors consulted by Reuters were split on whether Burnham would take a market-friendly approach. Last September, Burnham said Britain needed to move “beyond this thing of being in hock to the bond markets” — a comment he later said was taken out of context.
“In our view, a Burnham premiership would inherit a precarious fiscal situation with few tools to deliver meaningful change,” economists at Citibank said on Friday.
Starmer had publicly stated on Friday that he would compete in any formal leadership contest held to replace him. Meanwhile, former health minister Wes Streeting said he has secured the support of the 81 Labour lawmakers required to enter such a race. However, a senior party figure suggested Streeting might cut a deal with Burnham — possibly accepting a high-ranking role in exchange for staying out of the contest.
While Starmer’s inner circle argues that his 2024 national election landslide gives him a mandate to govern through 2029, business minister Peter Kyle acknowledged on Sunday that the prime minister was thinking carefully about “the political challenges that he faces in this moment.”
Should Starmer step up to a podium at Downing Street on Monday to announce a departure date, he would join a long line of recent British leaders to exit under pressure. If Burnham succeeds him, he would become the seventh person to hold the office of prime minister since the Brexit referendum — a vote to leave the European Union that took place ten years ago this week.
That rate of leadership turnover is the highest Britain has seen in nearly two centuries, reflecting the deep difficulty successive governments have faced in improving living standards, public services, and controlling illegal immigration.
The political advisory group Eurasia suggested the most favorable scenario would be for Starmer to announce a September departure, allowing him to attend a planned UK-European Union summit in July while giving Burnham adequate time to prepare for taking office.
