Former Foreign Office Chief Claims Sir Olly Robbins Was Scapegoated in Mandelson Vetting Crisis

Lord Simon McDonald, a former permanent secretary of the Foreign Office, has accused Downing Street of 'throwing' Sir Olly Robbins 'under the bus' following the revelation that security vetting failures were overruled for Peter Mandelson. Speaking on BBC Radio 4's Today programme, Lord McDonald suggested that Prime Minister Keir Starmer's administration sought a quick 'scalp' to manage the fallout. The controversy has been described by the former chief as the most significant crisis in the diplomatic service in four decades.

The Details

Sir Olly Robbins, the most senior civil servant at the Foreign Office, was forced to resign on April 16, shortly after an investigation by The Guardian revealed that the Foreign Office had overruled a 'no' verdict from UK Security Vetting (UKSV) regarding Peter Mandelson's security clearance. Lord McDonald, who led the Foreign Office from 2015 to 2020, stated that the speed of Robbins' departure indicates a lack of fairness and a desire by Number 10 to assign blame rapidly.

Prime Minister Keir Starmer has expressed outrage, claiming he was 'staggered' and 'furious' to learn that he had told Parliament due process had been followed while Mandelson had actually failed the vetting process. Starmer described the failure to inform him as 'unforgivable.' However, reports indicate that Cabinet Secretary Antonia Romeo was aware of the vetting failure in late March, several weeks before the Prime Minister was notified.

Lord McDonald challenged the government's narrative, arguing that while specific confidential details of vetting are not shared with political leaders, an outright failure must be conveyed to the political level. He suggested that the failure to do so implies the situation was more complex than Downing Street has admitted. This contradicts the official account and fuels opposition claims that the Prime Minister may have been misleading Parliament.

Adding to the complexity, allies of Sir Olly Robbins have questioned whether he ever saw the full UKSV recommendation to deny clearance. Some suggest he may have only been presented with specific risks rather than the definitive 'no' verdict, potentially shielding him from the full weight of the decision to overrule the agency.

In response to the crisis, Darren Jones, the Chief Secretary to the Prime Minister, labeled the decision to overrule vetting recommendations as 'unacceptable.' As a direct result, the government has suspended the Foreign Office's authority to overrule such security recommendations in the future.

Context

The crisis centers on the appointment of Peter Mandelson as the UK's ambassador to the United States in December 2024. Mandelson, a high-risk appointment due to previous ethical resignations and his association with Jeffrey Epstein, took the post in February 2025. He was subsequently removed in September 2025 after evidence emerged that he had lied about his links to Epstein.

Further complicating the matter, Mandelson was arrested on February 23, 2026, on suspicion of misconduct in public office. This followed the release of US Justice Department documents suggesting Mandelson may have passed market-moving government information to Epstein between 2009 and 2010. Although he was released after questioning and denies any wrongdoing, he has not been charged.

Standard government vetting is conducted by a Cabinet Office-overseen agency that provides risk-based assessments. While these are not binary 'pass/fail' grades, a recommendation against clearance is typically stringent. The decision by the Foreign Office to bypass this recommendation in Mandelson's case has created a systemic crisis of confidence within the diplomatic corps.

What's Next

The political tension is expected to peak on Monday, when Prime Minister Keir Starmer is scheduled to make a formal statement to Parliament. This event is being characterized by critics as a 'judgment day' for the Prime Minister's leadership.

Following the Prime Minister's statement, Sir Olly Robbins is expected to appear before the Foreign Affairs Committee on Tuesday. Chaired by Dame Emily Thornberry, the committee will seek to clarify Robbins' role in the vetting overrule and whether he was fully briefed on the UKSV's rejection.

Opposition leaders are already calling for Starmer's resignation. Conservative leader Kemi Badenoch has asserted that the Prime Minister has 'no one left to sack,' while Liberal Democrat leader Ed Davey has called for a Privileges Committee investigation to determine if the Prime Minister intentionally misled Parliament regarding the adherence to due process.
