UK Prime Minister Keir Starmer faced mounting pressure to resign on Friday following revelations that his appointment of Peter Mandelson as Ambassador to the United States proceeded despite Mandelson failing high-level security vetting.
The scandal has intensified after it emerged that Foreign Office officials used a rarely exercised authority to overrule the formal recommendation of UK Security Vetting (UKSV) in early 2025.The fallout has already led to the departure of the Foreign Office’s top civil servant, Sir Olly Robbins, who resigned after Starmer reportedly “lost confidence” in him.
Senior minister Darren Jones confirmed that neither the Prime Minister nor the Foreign Secretary were informed of the failed security check until this week. Jones described the departmental override as a “failure of the state” and noted that Starmer was “furious” upon learning he had been kept in the dark while repeatedly assuring Parliament that due process had been followed.Opposition leaders have been swift to condemn the government’s handling of the matter.
Conservative Party leader Kemi Badenoch stated on X that “Starmer has betrayed our national security” and characterized the claim that the Prime Minister was unaware of the vetting failure as “preposterous.” Ed Davey, leader of the Liberal Democrats, added that Starmer must resign if it is proven he misled the public or Parliament.
The controversy is deeply rooted in Mandelson’s past ties to the late American sex offender Jeffrey Epstein. While Mandelson was sacked from the diplomatic post in September 2025 after further details of these ties emerged, the new revelations suggest he was granted access to sensitive material despite explicit warnings from security services.
Police are currently investigating allegations of misconduct in public office involving Mandelson, including claims that he leaked sensitive documents to Epstein during his time as a government minister in 2008.The government has promised to release further documents related to the vetting process in the coming weeks.
Prime Minister Starmer is expected to address Parliament on Monday to provide a full account of the timeline and the internal investigation into the Foreign Office’s actions.
