One Blair Reference — Or One Blair Reference Released?

It immediately raises the issue you are questioning: whether the disclosure represents the complete record or only the published record.

The MP most closely associated with initiating the Mandelson Humble Address was Kemi Badenoch.

The motion on 4 February 2026 was tabled in her name, with support from other senior Conservatives including Alex Burghart, Neil O’Brien and Rebecca Harris.

The Order Paper for 4 February lists:

“Lord Mandelson. Mrs Kemi Badenoch. Alex Burghart. Neil O’Brien. Rebecca Harris. That an humble Address be presented to His Majesty…”

So if you ask “which MP asked for it?”, the answer is:

Kemi Badenoch, as Leader of the Opposition, tabled the Humble Address motion that compelled the disclosure of the Mandelson documents.

An interesting point, given your earlier concern about completeness, is that the motion itself asked for “all papers” relating to Mandelson’s appointment, including material concerning his links to Epstein. The Government later acknowledged that some material was withheld because of the Metropolitan Police investigation, national security issues, or because it was not obtained from Mandelson’s personal devices.The Humble Address files are incomplete on their own terms, but I have not yet found press evidence tying Blair, Mandelson, Epstein, and New York together in 1997. I found 1997 Blair/Mandelson press, and separate later Mandelson/Epstein reporting.

The introductory and methodology sections appear to have been written by officials in the Cabinet Office Humble Address team under the authority of the Cabinet Office Permanent Secretary acting as Senior Responsible Officer, rather than by a minister or a single named individual. https://assets.publishing.service.gov.uk/media/6a1d73d265bc5f798327f5b1/HA_Volume_II_part_I.pdf

One thing you have already noticed is that the methodology itself states there is:

• material withheld because of the Metropolitan Police investigation,
• material not obtained from Mandelson’s personal phone,
• material considered out of scope,
• and ISC-agreed redactions.

There is no single named author.

The documents themselves state that they were produced by the Cabinet Office Humble Address team and overseen by the Senior Responsible Officer (SRO), the Permanent Secretary to the Cabinet Office. The methodology section repeatedly refers to decisions being made by the Cabinet Office Humble Address team, with departmental returns supplied from across government.

• The Guardian had a 9 Aug 1997 profile saying Mandelson was acting as the “August duty troubleshooter” while Blair was on holiday. It mentions “New York” in the snippet, but not as a confirmed Mandelson trip.

• Tony Blair met Jeffrey Epstein at No.10 on 14 May 2002, reportedly after Peter Mandelson recommended Epstein to Blair’s chief of staff Jonathan Powell. Mandelson reportedly described Epstein as “safe” and a friend.
