Starmer Faces Judgment Day Over Mandelson Vetting Scandal
Prime Minister Keir Starmer will address MPs on Monday in what allies are calling his 'judgment day' over the Peter Mandelson vetting scandal. Starmer appointed Lord Mandelson as UK ambassador to Washington despite the former cabinet minister's ongoing relationship with convicted sex offender Jeffrey Epstein and business ties to China. A leaked WhatsApp exchange suggests Downing Street may have known about vetting concerns as early as September, raising questions about whether Starmer misled Parliament. Olly Robbins, the top civil servant at the Foreign Office, was sacked over the affair.

Prime Minister Keir Starmer faces what senior government figures are describing as his "judgment day" on Monday when he will deliver a high-stakes statement to MPs over the Peter Mandelson vetting scandal, amid growing outrage and calls for his resignation from within and outside his party. Starmer appointed Lord Mandelson as UK ambassador to Washington despite the former cabinet minister having been sacked from government twice, maintaining an ongoing relationship with convicted sex offender Jeffrey Epstein, and having business links with China. The prime minister claims he was only informed on Tuesday that Mandelson had failed his security vetting, calling it "astonishing" and "unforgivable" that neither he nor other ministers were told before he stated in Parliament that due process had been followed. The scandal has already claimed one casualty: Olly Robbins, the top civil servant at the Foreign Office, who was sacked over the affair and is now taking legal advice. Robbins is expected to appear before the foreign affairs select committee on Tuesday in what could prove another damaging moment for Starmer, as he is understood to feel angry at what he believes to be his unfair treatment. However, a "smoking gun" WhatsApp exchange between Downing Street's then director of communications and The Independent suggests the prime minister's office may have been aware of vetting concerns as early as last September, raising questions about whether Starmer misled Parliament when he said due process had been followed in February. The controversy comes as Starmer was already bracing for what is expected to be a difficult set of local and devolved elections on May 7, with Labour MPs who had been agitating for change at the top stepping back from the brink just weeks ago. Deputy Prime Minister David Lammy sought to reassure the public on Sunday, telling the Guardian that voters wanted stability, not "a self-flagellating, internally focused" governing party, and that a leadership change followed by a general election would be damaging. Technology Secretary Liz Kendall defended Starmer, insisting he had "made the right calls" on major issues facing the country, but the prime minister's team acknowledges this week could be make-or-break if more damaging information emerges or if skeptical Labour MPs finally lose faith.
