The UK government is embroiled in controversy following revelations that Peter Mandelson was appointed as ambassador to the US despite failing his security vetting. Chief Secretary to the Prime Minister, Darren Jones, labeled the Foreign Office's decision to overrule security findings as 'utterly unacceptable' and has suspended their authority to make such judgments. This decision came after the Guardian reported that Mandelson's security clearance was denied in late January 2025, but the Foreign Office used its authority to override this recommendation. Opposition leaders, including Kemi Badenoch from the Conservative Party and Sir Ed Davey of the Liberal Democrats, have criticized Prime Minister Keir Starmer, demanding his resignation over perceived negligence in handling the situation. They argue that the Prime Minister should have been aware of Mandelson's failed vetting prior to his appointment. The fallout has also resulted in the removal of Sir Olly Robbins, the Foreign Office's top civil servant, who was in charge at the time of Mandelson's appointment. As Starmer attends international talks in Paris, the political ramifications of this scandal continue to unfold in Westminster.
