Prime Minister Demands Full Account After Security Vetting Override
Prime Minister Keir Starmer has issued a direct order to the Foreign Office, demanding a comprehensive explanation of how Lord Peter Mandelson was cleared to become the United Kingdom's ambassador to the United States. This directive follows the revelation that the Foreign, Commonwealth & Development Office (FCDO) took the extraordinary step of overruling a security vetting process that had initially denied the former Labour grandee clearance.
Prime Minister Unaware Until Recent Days
According to an official Government statement, Sir Keir Starmer was not informed that Lord Mandelson had been granted developed vetting clearance against the explicit advice of UK Security Vetting (UKSV) until earlier this week. Upon learning this information, the Prime Minister immediately instructed officials to establish the full facts surrounding why the vetting was granted. The Foreign Office has confirmed it is "working urgently" to comply with this request for a detailed account.
Sources within Downing Street have indicated that the Prime Minister is "absolutely furious" about the situation. The controversy stems from a report by The Guardian, which detailed that security officials had initially denied Lord Mandelson clearance. Critically, this denial occurred after the Prime Minister had already publicly named him as Britain's top diplomat in Washington. The Foreign Office then proceeded to override the security recommendation, a move described as highly unusual.
Contradiction in Public Statements
Sir Keir Starmer has previously insisted that due process was meticulously followed in Lord Mandelson's appointment. He has also stated that Lord Mandelson had been untruthful about the extent of his connections with the convicted paedophile financier, Jeffrey Epstein. The Prime Minister had publicly asserted that vetting carried out independently by the security services "gave him clearance for the role."
However, The Guardian reported that the peer was not granted approval following the secretive vetting process conducted by the Cabinet Office's UK Security Vetting unit last January. A Government spokesperson clarified the chain of responsibility, stating: "The decision to grant developed vetting to Peter Mandelson against the recommendation of UK Security Vetting was taken by officials in the FCDO." The spokesperson added that once informed, the Prime Minister acted swiftly to establish the facts to enable a planned update to the House of Commons.
Parliamentary Scrutiny Intensifies
Reports suggest Sir Keir Starmer may deliver a statement to Members of Parliament on Monday, although Number 10 has not confirmed this. Meanwhile, parliamentary scrutiny is escalating. Sir Olly Robbins, the Foreign Office's top civil servant, has been summoned to appear again before Parliament's Foreign Affairs Committee next week to provide a detailed explanation of events.
Dame Emily Thornberry, the senior Labour MP who chairs the committee, expressed her concerns publicly. "Perhaps he can tell us... was it his own idea, or was he being leant on elsewhere? Or was he, being a civil servant, was he getting direction from elsewhere, and if so, by whom?" she questioned in an interview with Sky News. Dame Emily also highlighted careful wording in a letter from Foreign Secretary Yvette Cooper, which noted the vetting was "concluded with DV clearance being granted by the FCDO," but did not explicitly mention an override. "It says he was vetted, and it says he was appointed, but it doesn't say it was overridden... people have basically been telling us half the story," she asserted.
Political Fallout and Calls for Resignation
The controversy has triggered significant political fallout, with opposition leaders calling for Sir Keir Starmer to stand down. Conservative leader Kemi Badenoch stated: "It is preposterous for Starmer to claim he did not know Mandelson failed security vetting. If the Prime Minister doesn't know what's happening in his own office, he shouldn't be in charge of our country. He should go."
Liberal Democrat leader Sir Ed Davey echoed this sentiment, arguing: "If this is true, the PM should've told Parliament at the earliest opportunity, not waited for the media to force the truth out. His failure to do that alone is surely a breach of the Ministerial Code." The Green Party and Reform UK have also joined calls for the Prime Minister's resignation.
Background of the Appointment and Epstein Links
Lord Mandelson, a political appointee rather than a career diplomat, was ultimately removed from his Washington role last September when further details surfaced regarding his relationship with Jeffrey Epstein, who died in 2019. Sir Keir Starmer has faced sustained criticism over the initial decision to appoint Lord Mandelson, given it was known that his dealings with Epstein continued after the financier's conviction for child sex offences.
Questions over the Prime Minister's judgment intensified last month when the first batch of released documents showed he was warned of a "general reputational risk" associated with Lord Mandelson's Epstein links before announcing the ambassadorship. This warning came from initial Cabinet Office checks based on public information.
The subsequent, highly confidential background vetting by security officials occurred after the announcement but before Lord Mandelson assumed his role in February 2025. The results of this process are binary—clearance or denial—and the detailed information, including any concerns, is never shared with ministers. According to The Guardian, Foreign Office officials invoked a rarely used authority to override the denial, informing Lord Mandelson of his clearance days later.
Internal Accountability and Union Response
Further documents related to the appointment are expected to be released following pressure from MPs. In February, Sir Keir Starmer stated that Lord Mandelson had been cleared by security vetting, while criticising the process for failing to uncover the peer's falsehoods. Around the same time, Morgan McSweeney resigned as the Prime Minister's chief of staff, taking "full responsibility" for providing advice that led to the "wrong" appointment decision. McSweeney also called for the vetting process to be "fundamentally overhauled."
Mike Clancy, general secretary of the Prospect trade union representing UKSV officers, expressed dismay at the situation. He stated it was "deeply unfortunate" that Downing Street had "allowed the impression to circulate that the vetting of Peter Mandelson had not been done correctly by UK Security Vetting." Clancy defended civil servants, noting they "cannot speak publicly, and deserve ministers to take responsibility for the decisions they take and not to seek to deflect blame on to them."
