Starmer would have blocked Mandelson role over vetting failure, says Lammy

Deputy prime minister says it is inexplicable' top civil servant kept Downing Street in dark

Keir Starmer would have blocked Peter Mandelson from serving as the UK's ambassador to Washington had he known he failed security vetting, David Lammy has said, as he attempted to shore up the prime minister amid damaging fallout from the row.

In his first public comments on the vetting affair, Lammy said it was inexplicable" that Oliver Robbins, the former top civil servant who was forced out of the Foreign Office this week, had opted to leave Downing Street in the dark over the outcome.
