Question to the Cabinet Office:

To ask the Minister for the Cabinet Office, with reference to the oral evidence of 3 November 2025 to the Foreign Affairs Select Committee by the Cabinet Secretary and the Permanent Under-Secretary at the Foreign, Commonwealth and Development Office, if he will publish the report given to the Prime Minister on the appointment of Lord Mandelson.

Due diligence was undertaken prior to the appointment of the former Ambassador to the United States, and was part of an established process to collate relevant information as part of the identification and selection of the appointee.

In line with the practice across multiple administrations, the government does not publish such material.

I refer the Hon. Member to the Cabinet Secretary’s letter of 30 October 2025 to the Public Administration and Constitutional Affairs Committee, which sets out the process and describes the information contained in the due diligence report: https://committees.parliament.uk/publications/50019/documents/269409/default/
