Mandelson files reveal pattern of disloyalty, documents show
15 reported4 unconfirmed
Thousands of documents released on June 1, 2026, reveal a pattern of disloyalty and self-interest by Peter Mandelson, according to a single-source report from The Guardian. The files include a handwritten note to then-foreign secretary David Lammy promising “You won’t regret appointing me,” and emails begging ministers to vote for him as Oxford chancellor. The documents also show Mandelson privately criticizing Labour figures including Wes Streeting, Pat McFadden, and Prime Minister Keir Starmer. The release occurred at 2pm, limiting time for MPs to scrutinize them before a Commons statement by Chief Secretary to the Prime Minister Darren Jones 90 minutes later. The report notes that Mandelson refused to hand over his phone, and Morgan McSweeney’s phone was stolen, resulting in missing messages. The source article is from The Guardian and has not been cross-referenced with other outlets.
