History

Historical Context

After Prime Minister Keir Starmer appointed Peter Mandelson as U.S. ambassador in February 2025, UK Security Vetting denied him clearance on 28 January 2025. The Foreign Office overrode the decision within 48 hours, and Olly Robbins was dismissed in April 2026 when the override became public. The episode revives long-standing doubts about political interference in UKSV vetting.
