Former Foreign Office Chief Claims Political Pressure to Approve Mandelson as US Ambassador

Sir Olly Robbins, the former head of the Foreign Office, testified on April 21, 2026, that he faced significant political pressure from Prime Minister Keir Starmer's office to expedite Peter Mandelson's appointment as UK ambassador to Washington. This testimony comes after Robbins was fired last week following revelations that Mandelson had been granted security clearance despite failing the government's official vetting process. The claims have intensified calls for Starmer's resignation as opposition leaders allege the Prime Minister misled Parliament.

The Details

Testifying before the House of Commons Foreign Affairs Committee, Robbins described an 'atmosphere of pressure' and a 'very, very strong expectation' that Mandelson be installed in Washington as quickly as humanly possible. The urgency, according to Robbins, was driven by the need to have the ambassador in place for the start of President Trump's second term in January 2025.\n\nRobbins revealed that the UK Security Vetting (UKSV) agency had viewed Mandelson as a 'borderline case' and was leaning toward recommending against his clearance. Despite this, Robbins decided to grant the clearance, asserting that his decision was based on advice that the associated risks could be managed. He explicitly stated that the security concerns flagged by the vetting agency did not relate to Mandelson's well-known associations with Jeffrey Epstein, though he declined to disclose the specific nature of the risks.\n\nPrime Minister Keir Starmer has rejected the implication that he was aware of the vetting failure at the time of the appointment. Starmer described it as 'staggering' that officials did not inform him of the security concerns, claiming he only became aware of them last week. Robbins countered this by stating that standard rules prevent the sharing of sensitive vetting details except in exceptional circumstances.\n\nRobbins' firing occurred last week, shortly after the government confirmed that Mandelson had indeed been approved against the UKSV recommendation. In the wake of the testimony, Conservative Party leader Kemi Badenoch called the revelations 'devastating' and argued that the failure to follow due process constitutes a resigning offense.\n\nMandelson's tenure as ambassador was short-lived; he was fired in September 2025, just nine months after taking the post. His removal followed the emergence of emails that revealed the depth of his relationship with Jeffrey Epstein was materially different from what had been disclosed during his appointment. One email showed Mandelson suggesting that Epstein's 2008 conviction was wrongful and should be challenged.

Context

Peter Mandelson, a Labour peer and former EU trade commissioner, was appointed to the US ambassadorship following Labour's election victory in July 2024. Starmer's staff had warned the Prime Minister prior to the appointment that Mandelson's friendship with Epstein posed a reputational risk. Additionally, Mandelson's business links to Russia and China had raised concerns, though his extensive trade expertise and elite contacts were viewed as strategic assets for managing relations with the incoming Trump administration.\n\nThe scandal has caused significant instability within the Labour party. Some lawmakers began calling for Starmer's resignation as early as February 2026, a period during which the party was already struggling with declining poll ratings.\n\nMandelson is currently under police investigation for suspected misconduct in public office. This follows the January 2026 release of U.S. Department of Justice documents containing emails that suggest Mandelson may have passed market-moving government information to Epstein in 2009. Mandelson was arrested in February 2026 and has denied any wrongdoing; he has not been formally charged.

What's Next

Prime Minister Starmer has acknowledged a 'wrong judgment' in selecting Mandelson for the role and has ordered a comprehensive review into the security risks resulting from Mandelson's access to sensitive information while serving as ambassador. He maintains that he would have withdrawn the appointment had he been informed of the vetting failure.\n\nPolitical pressure on Starmer is expected to mount as the House of Commons investigates whether the Prime Minister misled lawmakers regarding the timeline and nature of the security warnings. The outcome of the police investigation into Mandelson's suspected misconduct in public office will likely further influence the political fallout and potential calls for government accountability.
