Cabinet Office to release second tranche of Mandelson files
The UK Cabinet Office is set to publish a significant volume of correspondence regarding Peter Mandelson’s appointment as ambassador to the United States, following a House of Commons address. The release, triggered by a humble address process, will comprise more than 1,000 pages of emails and WhatsApp messages involving ministers, officials, and advisers during Mandelson’s tenure. However, the disclosure excludes a nine-page summary from UK Security Vetting (UKSV) that recommended denying Mandelson clearance due to concerns over his associations with figures in China, Russia, and Israel. The omission of the vetting report follows a request by the Metropolitan Police for certain documents not to be made public. Questions have been raised about the clearance process, particularly the lack of written records for security mitigations agreed upon by senior officials Olly Robbins and Ian Collard, who made their decision in late January 2025 based on oral briefings rather than the summary document.
