Material declassified under the 30-year rule

Most unpublished manuscript material in the Conservative Party Archive is subject to a general 30-year access restriction, while a few series are embargoed regardless of date without permission from the Conservative Party (see Access Restrictions).

Files de-classified under the 30-year rule (see Access Restrictions) since 2016, and any other files which the Conservative Party has agreed should no longer be restricted, are listed here:
