Mandelson received security briefings before vetting completed, documents show
Newly released documents reveal that Peter Mandelson, the UK’s ambassador designate to Washington, was receiving sensitive security briefings from the Foreign Office and had agreed to meet with the head of MI6 before finishing the developed vetting process. Declassified emails show Mandelson believed he could see secret documents without clearance because he was a privy councillor, though officials eventually decided clearance was needed. The files also document Mandelson’s internal criticism of Prime Minister Keir Starmer, whom he said tended to buckle under pressure. The approximately 1,500-page document release was triggered by a humble address process, but some documents were withheld due to national security concerns and a potential future prosecution by the Metropolitan Police. Omitted materials include a nine-page summary from UK Security Vetting and Mandelson’s completed declarations of interest form. It remains unclear whether the planned meeting with MI6’s chief, known as “C,” and the security briefings ultimately took place.
