Question to the Cabinet Office:
To ask the Minister for the Cabinet Office, when Ministerial private office records are transferred to National Archives; and whether some files are retained by the Department.
The Cabinet Office Records Selection Policy under the Public Records Act 1958 is available at https://www.gov.uk/government/publications/cabinet-office-records-selection-policy/cabinet-office-records-selection-policy-html#:~:text=The%20Cabinet%20Office%20Records%20Selection,selection%20of%20historic%20public%20records.
At the time of transfer to The National Archives, redactions can be made by the application of FOI exemptions that persist beyond 20 years or by provision of Section 3(4) of the Public Records Act. Any closures or retentions are made clear either within the open file or on The National Archives catalogue, which is available on line.
