Sir Olly Robbins, former top civil servant at the Foreign Office, was dismissed by Prime Minister Sir Keir Starmer in April 2025 over the security clearance process for Lord Mandelson as UK ambassador to the US. Robbins, represented by the FDA union, is seeking judicial review of the decision. Lord Mandelson received clearance despite internal concerns, took up the post in February 2025, and was removed seven months later.
