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

A former MI6 chief stated it was 'totally impossible' for the UK Foreign Office to mitigate risks posed by Peter Mandelson's associations with senior figures in China, Russia, and Israel during his tenure as UK ambassador to the US. Security concerns, revealed by the Guardian, led to Mandelson being denied developed vetting clearance in early 2025.
