Mitigating Mandelson risks would have been impossible, says former MI6 chief

Vetting of former UK ambassador to Washington warned of ties to senior figures in China, Russia and Israel

A former head of MI6 has said it would have been “totally impossible” for the Foreign Office to put in place mitigations to manage Peter Mandelson’s associations with senior figures in China, Russia and Israel when he was the UK’s ambassador to the US.

On Wednesday, the Guardian revealed some of the concerns that contributed to security officials recommending that Mandelson be denied developed vetting clearance in early 2025.
