British Prime Minister Keir Starmer is facing the gravest threat to his authority since taking office, after Health Secretary Wes Streeting resigned from the cabinet and Greater Manchester Mayor Andy Burnham moved to re-enter parliament to mount a formal leadership challenge. The twin developments, which unfolded within hours of each other last Thursday, have set Labour on a course toward a leadership contest that political observers say now looks all but inevitable.
Streeting, a 43-year-old politician associated with the centrist, Blairite wing of Labour, had long been seen as harbouring prime ministerial ambitions. His resignation letter acknowledged the scale of the country's difficulties, noting that "for the first time in our history the next generation faces a worse inheritance than the last." Within hours, Burnham — popularly known as the "King of the North" and consistently Labour's highest-polling politician — confirmed he would contest a by-election in Makerfield, a constituency in Greater Manchester, after the sitting MP Josh Simons announced he was vacating his seat to make way for him. Labour's party leadership has indicated it will not block Burnham's candidacy this time, after a previous attempt to re-enter parliament through a by-election in Gorton and Denton earlier this year was halted by the party's national executive committee.
The path has not been straightforward. Over a fraught week, multiple MPs whose seats had been linked to a Burnham candidacy declined to stand aside. The breakthrough came after Burnham spent two hours at Simons's home with his wife, discussing economic strategy and plans for government. Simons, just 32 years old, cited his disillusionment with the current direction of the party. "We are where the Democrats were in 2021, hurtling towards oblivion with an out-of-touch PM," he said. The Makerfield by-election, likely to be held in late June, presents its own risks: Reform UK, the anti-immigration party led by Nigel Farage, swept all of the constituency's local council wards in elections last week and has pledged to contest the seat aggressively.
The wider field of potential successors includes Deputy Prime Minister Angela Rayner, who had been forced to step back from frontline politics following a tax scandal but announced this week that the inquiry into her affairs had been closed with no findings against her, clearing her path to run. Home Secretary Shabana Mahmood, credited with reducing net migration sharply from its historic peak under the previous Conservative government, is also widely regarded as a serious contender, though she faces scepticism from Labour's left wing.
Starmer's difficulties are not solely internal. Last Thursday's political turmoil coincided with preparations for a major far-right march in London on Saturday, organised by activist Tommy Robinson — whose legal name is Stephen Yaxley-Lennon — and billed by him as the largest rally in British history. The Metropolitan Police deployed some 4,000 officers and facial recognition technology for what became one of the largest security operations in the capital in years. Analysts argue that Starmer's predicament reflects deeper structural problems in British governance: five consecutive prime ministers have failed to complete full terms, a combination of Brexit's aftermath, economic stagnation driven by energy price shocks and high debt, and a fragmented electorate that has turned toward the Greens, Reform UK, and the Liberal Democrats. "The traditional domination of British politics by the centre-left Labour Party and the centre-right Conservative Party looks like it is well and truly over," said Tim Bale, professor of politics at Queen Mary University, London. The United Kingdom, it appears, may be approaching its sixth prime minister in seven years.
