The Labour party has been plunged into significant political turmoil as Health Secretary Wes Streeting reportedly prepares to launch a leadership challenge against Prime Minister Keir Starmer. This development, which materialized precisely as the monarch’s state coach arrived at parliament for the king’s speech, has ended an unofficial political truce and ignited a frantic scramble within the party. Many Labour colleagues had previously assumed Streeting’s chance for the top job might have passed, with one MP likening him to a "David Miliband of this generation" – a long-time heir apparent who never made the final step.

Streeting’s ambition has long been an open secret within Labour circles, often a subject of frequent jokes, including self-deprecating ones from Streeting himself. Initially, his allies played down the prospect of a bid, hoping Starmer would step down or another candidate would emerge. However, two critical shifts occurred. Firstly, Starmer continued to hold on, despite an underwhelming "reset" speech and the resignation of several junior ministers, mostly allied with Streeting. Secondly, Downing Street and its allies began to brief with increasing vehemence, suggesting Streeting was a "busted flush," had "bottled it," or was unable to secure the necessary 80 MPs (20% of the parliamentary party) to trigger a contest. This was compounded by a brief, 16-17 minute meeting granted to Streeting by Starmer, perceived by some as a deliberate humiliation, akin to a "summons by the chief whip for a bollocking" in Tory parlance.

Despite these dismissals, Streeting’s camp maintained their resolve, describing their preparations as "planning, not plotting," aiming to be ready if a contest began. On Monday, Business Secretary Peter Kyle, a close friend of Streeting, publicly downplayed a bid by recounting a joint dinner and a viewing of 'The Devil Wears Prada 2', questioning if a man focused on a leadership bid would have time for such leisurely activities. However, by Tuesday night, Streeting’s supporters were reportedly calling MPs, urging them to hold their nerve and not believe negative press, insisting that Streeting still intended to challenge for the leadership.

A wave of resignations from junior ministers allied with Streeting signaled the intensifying pressure. These included Zubir Ahmed, the Glasgow South West MP and former surgeon, who publicly criticized Starmer's leadership; Jess Phillips, the Birmingham Yardley MP and safeguarding minister, who penned a stinging letter describing Starmer as too cautious; Joe Morris, the Hexham MP and Streeting’s parliamentary private secretary, whose resignation was seen as "firing the starting gun"; Alex Davies-Jones, the Pontypridd MP, who implored Starmer to set a timetable for his departure; and Chris Curtis, the Milton Keynes North MP and chair of the Labour Growth Group. Alan Gemmell, the Central Ayrshire MP, and Melanie Ward, the Cowdenbeath and Kirkcaldy MP, also resigned, with Ward stepping down from her role as PPS to David Lammy.

Starmer, for his part, has been actively calling ministers and MPs into his office, pleading with them not to allow a competition to be triggered, asserting that "a challenge would 100%" plunge the government into chaos and paralyze its ability to get things done. His cabinet allies, including Rachel Reeves, have echoed these warnings. Starmer's close allies believe he could not be bullied out and that Streeting would not be able to command the support of the parliamentary party and membership. Downing Street has insisted Starmer would fight any challenge, having just set out a program for government with 30 new bills.

The potential leadership contest has sparked a frantic search on the left of Labour for a candidate to oppose Streeting, with Ed Miliband, the energy secretary, and Angela Rayner, Starmer’s former deputy, identified as possible contenders. Andy Burnham, the Greater Manchester mayor, is favored by many on the soft left but currently lacks a parliamentary seat, making an immediate bid difficult. His allies have reportedly begun casting around for alternative plans, with "stopping Wes" being a top priority, fearful that a straight Starmer-Streeting contest could see Starmer win even if he came second, due to Labour’s preferential voting system. Some left-wing MPs might even back Streeting over Starmer in a direct contest, though others fear Streeting could end up like Owen Smith, whose political career ended after an unsuccessful leadership bid.

While Thursday was initially billed as the likely moment for Streeting's announcement, confirmation from his camp has been elusive. His only public comment on Wednesday was a pre-set tweet highlighting ministerial achievements, which annoyed some cabinet colleagues by emerging just before the king’s address. Amidst this uncertainty, Starmer's official spokesperson maintained that the Prime Minister had full confidence in his health secretary, though Northern Ireland Secretary Hilary Benn's earlier remark, "I don’t know, why don’t you ask him?" when questioned about Streeting's post, revealed underlying tensions. Some MPs are "very, very, very angry" at Streeting for destabilizing the party, while others criticize Starmer's perceived missteps in handling the crisis, including his desire to stay in power for 10 years and bringing back Gordon Brown and Harriet Harman. The immediate viability and timing of any leadership bid, and the full slate of potential contenders, remain highly complex and uncertain.
