Prime Minister Keir Starmer is rebuilding his front bench after a fortnight of resignations, but the rebellion within the Parliamentary Labour Party shows no sign of subsiding. Ninety-five Labour MPs had publicly called on Starmer to resign or to set a departure timetable by the close of business on Monday, according to a count by Politico Europe — enough, if every MP backed the same successor, to clear the threshold for triggering a formal leadership contest.
Starmer named former Treasury minister James Murray as Health Secretary on Saturday, replacing Wes Streeting, who resigned earlier in May with a public statement that he had "lost confidence" in the prime minister. Two junior ministers in the Cabinet Office were also reassigned over the weekend, and Downing Street confirmed on Sunday night that the Chief Whip would remain in post despite earlier reports that she had offered to step aside.
The crisis was triggered by Labour’s performance in the May 1 English local elections, in which the party lost nearly 1,500 council seats and Reform UK won 1,454 — the strongest result for an insurgent right-wing party in modern English local politics. Starmer has so far refused to set a departure timetable and told a Sunday-morning interview that he would contest any leadership challenge.
No clear successor has emerged. The 95 MPs calling for his exit do not yet coalesce around a single name; at least 81 sitting Labour MPs would need to declare for a single challenger to formally trigger a contest under the party’s rules. Soundings of cabinet ministers suggest that Deputy Prime Minister Angela Rayner, Foreign Secretary David Lammy and Streeting are the names being weighed by parliamentary colleagues.
Markets have so far paid only modest attention. Sterling closed broadly unchanged against the dollar on Friday at $1.296 and 10-year gilt yields are roughly six basis points lower than a fortnight ago. UK CDS spreads have edged wider since the local elections but remain below their levels during the 2022 mini-budget crisis.
Within the parliamentary party, much of the debate is now focused on procedure rather than personality. Several MPs have asked the National Executive Committee to clarify whether the September party conference would be brought forward to accommodate a contest; the NEC is scheduled to meet on Wednesday. Allies of the prime minister maintain that any move to topple him without a clear alternative would hand the next general election to Nigel Farage’s Reform UK.
Reform itself has been quiet but visible. Farage spent the weekend on a visit to former Red Wall constituencies, including Bassetlaw and Mansfield, and announced a fresh set of policy commitments on planning reform and migration to be detailed on Wednesday.
