History

Historical Context

In January 2016 Theresa May appointed veteran diplomat Kim Darroch as UK ambassador to the United States; a July 2019 leak of his candid cables about the Trump administration forced his resignation, ending a 40-year diplomatic career. The scandal spurred a Commons inquiry and, by December 2024, Keir Starmer faced a motion rejecting an ethics probe into Peter Mandelson’s U.S. ambassadorship, showing Parliament’s scrutiny of diplomatic appointments.
