The emerging account of Peter Mandelson’s appointment as US ambassador raises a question not of process, but of judgment (Revealed: Mandelson failed vetting but Foreign Office overruled decision, 16 April). The prime minister was warned repeatedly. Briefings in November and December 2024 flagged reputational risks, including well-documented associations and potential exposure if the appointment went wrong. Keir Starmer’s national security adviser raised concerns directly. Yet the appointment proceeded at pace.
Security vetting did not introduce uncertainty; it confirmed it. Developed vetting, even when expedited, typically requires several weeks. Factoring in the Christmas slowdown, the effective assessment window was little more than a fortnight. A refusal reached on that timescale is unlikely to reflect marginal doubt; it suggests concerns identified early and clearly. Yet by 6 January, Mandelson was already operating with a security pass marked for developed vetting access. The system was behaving as if clearance were assured before the decision had been taken.
