Senior Labour MPs have launched a devastating attack on Prime Minister Keir Starmer following his extraordinary admission that he was aware of Peter Mandelson's ongoing relationship with convicted sex offender Jeffrey Epstein before appointing him as US ambassador. The revelation has plunged the Labour government into its most severe crisis since taking office, with multiple senior figures questioning Starmer's judgment and leadership.
Damning Admission Sparks Leadership Crisis
After months of evasion and careful political maneuvering, the Prime Minister was finally forced to concede that he proceeded with Mandelson's controversial diplomatic appointment despite receiving explicit warnings from officials. Downing Street has confirmed that Sir Keir knew the Labour peer maintained his friendship with Epstein even after the financier's 2008 conviction for child sex offences, and was aware that Mandelson had continued staying at Epstein's properties during and after his prison sentence.
Mounting Pressure From All Sides
The admission has horrified Labour MPs across the political spectrum, with one former minister describing it as 'one of the worst days of Starmer's premiership so far'. Multiple senior figures have now openly called for the Prime Minister's resignation, marking a significant escalation in the internal party rebellion that has been simmering for months.
A former minister told the Guardian: 'It's time for a fresh start. The Prime Minister's judgment in this matter has been catastrophically flawed, and I'm no longer certain I could support him in a confidence vote.'
Allies Struggle to Defend Indefensible
Even Starmer's closest political allies have found themselves unable to mount an effective defence. One cabinet minister admitted privately that Mandelson's appointment was 'very hard to defend' and represented 'yet another self-inflicted wound' for the embattled Prime Minister. Another minister described the situation as feeling 'terminal' for Sir Keir's leadership, while a third observed that his performance during Prime Minister's Questions was 'physically painful to watch'.
Vetting Process Under Intense Scrutiny
It has emerged that when Mandelson was appointed towards the end of 2024, Sir Keir received a two-page document from the Cabinet Office ethics team that summarised the peer's 'well-rehearsed conflicts of issues and previous scandals'. According to sources, this document included clear references to Mandelson's connections with Epstein, with one insider describing the vetting material as appearing to be 'cut and pasted from Google'.
Public Domain Warnings Ignored
The documentation reportedly contained information that was already in the public domain, including a warning from a 2019 internal JP Morgan report that stated: 'Jeffrey Epstein appears to maintain a particularly close relationship with Prince Andrew… and Lord Mandelson, a senior member of the British government.' Specific details about Mandelson's visits to Epstein's homes, including stays in 2009 while the financier was still incarcerated, were also clearly outlined in the vetting papers.
Commons Clashes and Demands for Accountability
During angry exchanges in the House of Commons, the Prime Minister claimed he had been 'lied to repeatedly' by Mandelson and insisted that proper procedures had been followed. However, he now faces intense questioning from all political quarters about his personal judgment in proceeding with the appointment despite the clear warnings.
Badenoch's Devastating Intervention
Kemi Badenoch, who forced the Prime Minister's admission through a rare parliamentary procedure, delivered a scathing assessment of his decision-making. She declared: 'The national security issue was appointing Mandelson in the first place... This is not about national security; this is about the Prime Minister's job security.' Her intervention compelled the government to release key documents surrounding the controversial diplomatic appointment.
Calls for Wider Resignations
The crisis has extended beyond the Prime Minister himself, with growing demands for his chief aide, Morgan McSweeney, to resign. McSweeney is understood to have played a pivotal role in Mandelson's appointment, and multiple MPs have stated they have 'lost confidence' in him, declaring his position 'untenable'.
Defensive Measures and Further Revelations
Sir Keir has attempted to defend his actions by emphasising that he moved swiftly to dismiss Mandelson last year when it emerged the peer had advised Epstein to appeal against his conviction. The Prime Minister told Parliament: 'I am as angry as the public about the conduct of my former ally. He lied repeatedly to my team when asked about his relationship with Epstein… I regret appointing him.'
Committee Criticism and Historical Context
Dame Emily Thornberry, Labour chairman of the foreign affairs committee, suggested the entire fiasco could have been avoided if the Prime Minister had allowed proper parliamentary scrutiny. She argued that instead of rushing through the political appointment, Mandelson should have been interviewed by relevant committees, a process that might have exposed the depth of his Epstein connections earlier.
John McDonnell, former shadow chancellor under Jeremy Corbyn, delivered perhaps the most damaging blow from within Labour's own ranks. He stated publicly: 'I've never called for him to go but I have lost confidence in him. The decisions around Mandelson pushed me over the edge.'
Unanswered Questions and Political Fallout
When pressed about whether the vetting process had specifically highlighted Mandelson's ongoing relationship with Epstein, the Prime Minister confirmed: 'Yes, it did... As a result, various questions were put to him.' Sir Keir maintains that the released documents will demonstrate how Mandelson 'completely misrepresented the extent of his relationship with Epstein and lied throughout the process.'
The scandal represents the most significant threat to Starmer's leadership since he entered Downing Street, with the combination of damning admissions, internal party rebellion, and questionable judgment creating a perfect political storm that shows no signs of abating. The Prime Minister's ability to survive this crisis will depend on whether he can regain the confidence of his parliamentary party and convince the public that his judgment remains sound despite this catastrophic error.
