From pollution to policing – can Sadiq Khan clean up London?

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 ‘constant pressure’ to get Mandelson in post as US ambassador as soon as possible, and claimed Downing Street took a ‘dismissive’ attitude to vetting. It came a day after Keir Starmer accused Robbins of ‘obstructing the truth’ about the vetting process in a high-stakes appearance in parliament.

Keir Starmer says it is ‘staggering’ and ‘unforgivable’ that he was not told Peter Mandelson had failed security vetting before taking up the role of US ambassador. The comments follow a Guardian investigation that exclusively revealed Mandelson had initially been denied clearance after a background check by security officials, but that the decision was overruled by the Foreign Office.
