The BBC understands Sir Keir Starmer and Foreign Secretary Yvette Cooper lost confidence in Sir Olly Robbins and was effectively sacked after a Guardian investigation revealed Mandelson had not been security cleared.

The PM is facing calls to resign amid claims he misled MPs when he told them „full due process“ had been followed.

Senior minister Darren Jones said Sir Keir had not been told of the vetting recommendation until Tuesday this week, had not misled MPs and would not be resigning.
