March 11 (UPI) -- The British Cabinet Office has released files from its investigation into former ambassador to the United States Peter Mandelson on Wednesday as it digs into his ties to deceased sex trafficker Jeffrey Epstein.

The first batch of documents revealed that Mandelson may have been briefed on classified information before being given security clearance when he was appointed as ambassador. They also show that he requested a large government payout when he was terminated last year.

Mandelson was arrested and then released last month in London over suspicion of misconduct in public office. The allegation stems from emails released in the Epstein files in which Mandelson appears to be sharing market-sensitive confidential information with Epstein.

Documents released by the Cabinet Office share some details after his appointment as ambassador in December 2024. Within days of his being appointed, the Foreign, Commonwealth and Development Office offered to brief Mandelson on highly classified information while he was still being vetted.
