Early reports suggest that while there will be a significant number, the documents won't, however, contain any record to mitigate serious security concerns and flags raised over his appointment.They come after the Prime Minister acquiesced to demands from MPs to release documents relating to Lord Mandelson's appointment in 2024 after questions over how the peer was vetted and what was known about his links to paedophile Jeffrey Epstein. Mr Starmer has repeatedly apologised to Epstein’s victims over the saga and claimed the New Labour architect lied to him.But the scandal has engulfed his government in recent months, sparked fury among backbench MPs, and called Mr Starmer’s judgement into question. A government spokesperson said: "We are committed to complying with the humble address in full. The second tranche of documents will be among the largest publications ever laid in parliament. That reflects the transparent and thorough process we have followed, in line with established precedent for humble addresses."A government spokesperson said: "We are committed to complying with the humble address in full.

Critics say too much information is expected to be redacted from the release. Some information cannot be released as it may compromise a police investigation into Peter Mandelson.Asked about the criticism, Mr Murray told Sky News: “I think the level of transparency is going to be unprecedented. The volume of information that's going to be put out is unprecedented. It's right, we do that. We've been very clear that the appointment of Mandelson was wrong. Parliament then decided that this information would be made public. The government's fully complying with that and it's important that we honour that commitment to transparency.”James Murray said the files would include an 'unprecedented' amount of information(Image: Ben Bauer/PA Wire)Today07:43 BSTMandelson files reportedly detail lack of assurances over national securitySeveral sources cited by The Guardian reportedly said that Mandelson had been asked to provide assurances over commercial conflicts of interest before he was handed the ambassador role.However, they said the same was not required for matters of national security.‌
