Takeaways from former top UK official’s testimony on Mandelson’s appointment

A former top British official has revealed that Prime Minister Keir Starmer’s office pushed for scandal-tainted politician Peter Mandelson to become Britain’s ambassador to Washington despite security concerns, amplifying a controversy that continues to plague the prime minister’s leadership.

Olly Robbins, the former head of the Foreign Office who was fired by Starmer last week, testified before Parliament’s Foreign Affairs Committee on Tuesday that there was “very, very strong expectation” from Downing Street that Mandelson “needed to be in post and in America as quickly as humanly possible.”

Robbins defended his decision to approve Mandelson for the diplomatic role despite being advised against it during security vetting, saying his department followed correct procedures. His testimony, however, has only intensified scrutiny of Starmer’s judgment and fueled calls for the prime minister’s resignation.

The controversy began when Starmer appointed Mandelson, a veteran Labour politician and friend of convicted sex offender Jeffrey Epstein, as ambassador in December 2024. Starmer later fired Mandelson after documents emerged showing the ambassador had maintained much closer ties to Epstein than previously disclosed.

In his testimony, Robbins described significant political pressure surrounding Mandelson’s appointment. He told lawmakers that Downing Street displayed a “dismissive attitude” toward the security vetting process, showing interest only in when – not whether – Mandelson would be cleared.

Robbins revealed that security vetting was still incomplete when Mandelson’s appointment was announced. Despite this, the U.S. government had accepted the nomination, and Mandelson was granted access to classified briefings before his security clearance was finalized.

A central dispute has emerged between Robbins and Starmer over communication about security concerns. Starmer claimed he was “furious” upon learning last week that Mandelson had failed security clearance, saying he fired Robbins for withholding this crucial information.

Robbins countered that Foreign Office confidentiality rules prevented him from informing the prime minister directly about his decision to override the security team’s recommendation. He stated that even he was not shown the vetting panel’s full report on Mandelson due to the secretive nature of the process.

According to government sources, vetting officials provide recommendations using a traffic light system – green, yellow, or red – to indicate whether clearance should be granted. Robbins testified he never saw this document but was briefed that vetting officials considered Mandelson a “borderline case” and were “leaning towards recommending that clearance be denied.” Nevertheless, Foreign Office officials determined these unspecified risks could be managed.

Robbins explicitly stated that the security concerns about Mandelson were unrelated to his ties to Epstein. The controversy over these connections emerged separately after files released in Washington suggested Mandelson had sent market-sensitive information to Epstein following the 2008 financial crisis, when Mandelson served as the UK’s business secretary.

A “due diligence report” released to Parliament last month revealed that civil servants had flagged “reputational risks” associated with appointing Mandelson to the high-profile diplomatic post. The report cited not only his Epstein connections but also troubling business ties to Russia and China, along with his resignations from two previous Labour governments over money and ethics scandals.

Conservative leader Kemi Badenoch has seized on Robbins’ testimony, calling it “devastating to Keir Starmer” and “inconceivable” that nobody in Starmer’s office knew Mandelson had failed security clearance. Badenoch has accused the prime minister of misleading Parliament, stating it is “absolutely clear that ‘full due process’ was not followed.”

The continuing controversy comes at a challenging time for Starmer, with polling consistently showing declining public support for his leadership. Keiran Pedley, director of politics at polling firm Ipsos, noted that while Starmer’s response to the Iran war had temporarily diverted attention from questions about his leadership, “that may no longer be the case.”

The prime minister now faces a potential referendum on his leadership in upcoming local elections across England, Scotland, and Wales, which political analysts expect to deliver particularly unfavorable results for the Labour Party.
