The former official was fired in April over Lord Mandelson's vetting to be the UK's ambassador to the US.

The top civil servant at the Foreign Office sacked by Sir Keir Starmer over Lord Mandelson's vetting to be US ambassador is taking legal action over his dismissal. Sir Olly Robbins was fired earlier this year, after it emerged the peer had been granted security clearance for the role despite concerns raised by vetting officials. Sir Olly is now seeking a judicial review of the decision to dismiss him, according to the FDA, the union for senior civil servants representing him in the action. The union said the sacking had taken place without "even the semblance of a fair process" and risked damaging the civil service. A government spokesperson said: "We do not comment on legal proceedings." Lord Mandelson was announced as the UK's ambassador to the US in December 2024, before in-depth vetting had been carried out, and formally took up the role in February 2025 after being granted security clearance. Just seven months later, he was sacked after further information emerged about his previous friendship with the late convicted sex offender Jeffrey Epstein. Sir Olly was sacked in April this year, in the wake of a Guardian story that revealed the peer's security clearance had been granted despite vetting officials raising concerns, with the prime minister later saying he was "furious" he had not been informed at the time. Sir Keir has previously said he sacked Sir Olly after not accepting his explanation for why clearance was granted, telling MPs in April: "I did ask him, and I did not accept his explanation. That is why I sacked him."
