Prime Minister's Statement on Security Concerns
LONDON, April 20 (Reuters) - British Prime Minister Keir Starmer on Monday said he had asked the group overseeing security standards across government to examine any security concerns raised during Peter Mandelson's tenure as ambassador to the United States.
Lack of Communication on Vetting Clearance
Starmer told lawmakers it was staggering that he had not been told that Mandelson had failed his security vetting clearance, even when he ordered a review into the process.
Expansion of Security Vetting Review
"I can tell the house that I've now updated the terms of reference for the review into security vetting to make sure it covers the means by which all decisions are made in relation to national security vetting," he said.
Additional Government Actions
The British premier added: "Separately, I've asked the government security group in the Cabinet Office to look at any security concerns raised during Peter Mandelson's tenure."
