Starmer Tells Commons Foreign Office 'Deliberately' Withheld Mandelson Vetting Info

UK Prime Minister Keir Starmer told the House of Commons on April 20, 2026 that officials in the Foreign, Commonwealth and Development Office had withheld information about Peter Mandelson’s failed security vetting from senior ministers, telling MPs that “a deliberate decision was taken to withhold that material from me.”¹⁴⁵

In his statement, Starmer said: “I should not have appointed Peter Mandelson.” He added that if he had known, before Mandelson took up his post, that United Kingdom Security Vetting (UKSV) had recommended that developed vetting be denied, “I would not have gone ahead.”⁴

Starmer’s Statement to MPs

In his Commons statement, the prime minister sought to push the political blame onto the Foreign Office bureaucracy, saying it “beggars belief that throughout the whole timeline of events officials in the Foreign Office saw fit to withhold this information from the most senior ministers.”⁴ Pressed by MPs on whether the omission was an oversight, he said: “This was not a lack of asking. This wasn’t an oversight. It was a decision taken not to share that information on repeated occasions.”⁵ Mandelson, a senior Labour figure and former cabinet minister, was the UK’s most prestigious diplomatic appointment when he took up the Washington role in February 2025.

Starmer fired Mandelson from the ambassadorship in September 2025 after newly released DOJ documents revealed the depth of his ongoing relationship with Jeffrey Epstein, including communications that continued after Epstein’s 2008 conviction. UK police arrested Mandelson in February 2026 on suspicion of misconduct in public office related to passing sensitive government information to Epstein.

The latest controversy emerged on April 16, when reports surfaced that Mandelson had failed his security vetting before the appointment but that Foreign Office officials had overruled the recommendation and cleared him for the role.³

Robbins to Face Foreign Affairs Committee

The political fallout was set to continue on April 21, when Olly Robbins, the former permanent secretary at the Foreign Office, was scheduled to give evidence to the House of Commons Foreign Affairs Select Committee about his role in the appointment.

According to UK media, Labour MP Emily Thornberry, who chairs the committee, had invited Robbins to testify about how the vetting recommendation was overruled and what officials told ministers about the security findings.

Opposition Response

Conservative leader Kemi Badenoch and Liberal Democrat leader Sir Ed Davey had already accused Starmer of misleading Parliament when news of the vetting failure first emerged on April 16. Badenoch said Starmer had given Parliament inaccurate information about whether due process was followed, while Davey called the entire affair a “catastrophic error of judgment.”³

Starmer’s Commons statement attempted to redirect responsibility toward the Foreign Office, but did not name individual officials he held accountable for the decision to overrule the vetting recommendation.

Context

The Mandelson scandal has cost Starmer two of his most senior aides. Chief of staff Morgan McSweeney and communications director Tim Allan both resigned earlier in 2026 over the handling of the appointment.

The scandal has rolled on for months, fueled by a steady stream of new disclosures from US-released DOJ documents. Among the most damaging: revelations that while serving as UK Business Secretary, Mandelson tried to arrange access to 10 Downing Street and the House of Lords for a 15-year-old “goddaughter” of Epstein while Epstein was in prison.
