The claim "Labour Members have given up on the Prime Minister" is strongly supported by the available evidence: 1. **Over 100 Labour MPs** (roughly a quarter of the Parliamentary Labour Party) publicly called for Starmer to go, with many signing a letter demanding a change of leadership. Some had signed a letter backing Starmer just the previous month but had since withdrawn their support. 2. **Senior Cabinet ministers** — including Foreign Secretary Yvette Cooper, Home Secretary Shabana Mahmood, Transport Secretary Heidi Alexander, and Energy Secretary Ed Miliband — privately told Starmer he needed to set out a timetable for his departure. 3. **The Chief Whip, Jonathan Reynolds**, conveyed the strength of feeling on the Labour benches that there should be an "orderly transition." 4. **Andy Burnham** had secured the backing of more than 201 Labour MPs (more than half the Parliamentary Labour Party) for a leadership challenge, according to the Observer. 5. **Labour grandees** including former Home Secretary Alan Johnson and Lord Falconer publicly said Starmer should step aside, with Falconer stating Starmer had "absolutely no authority left." 6. **Starmer himself** acknowledged in his resignation statement that his party was asking "whether I am best placed to lead us into the next general election" and that he had "heard the answer of my parliamentary party to that question." 7. The pressure culminated in **Starmer announcing his resignation** on the same day (Monday, June 3, 2026), saying he would remain as caretaker PM while a leadership contest took place. While "given up" is a colloquial phrase that could be seen as subjective, the underlying factual basis — that Labour MPs had broadly lost confidence in and withdrawn support from the Prime Minister — is well-documented. Over 100 Labour MPs publicly called for his resignation, multiple Cabinet ministers told him to go, the Chief Whip conveyed the loss of confidence on the benches, and the PM himself acknowledged that his parliamentary party no longer believed he was best placed to lead them.
