The Foreign Office chief sacked over the Peter Mandelson security vetting scandal has finally given his side of the story in an explosive appearance before MPs. Olly Robbins told the foreign affairs select committee that he faced âconstant pressureâ to get Mandelson in post as US ambassador as soon as possible, and claimed Downing Street took a âdismissiveâ attitude to vetting. It came a day after Keir Starmer accused Robbins of âobstructing the truthâ about the vetting process in a high-stakes appearance in parliament.
