There are files concerned with the Reconstruction Committee, the Ministry of Reconstruction, the Supreme War Council during the First World War, and various International Conferences. Some of the files relating to the Peace Conference (1919 to 1920) are those of the Paris Office of the War Cabinet. There are also files of Prime Minister's minutes dating from Atlee's tenure (1945-1951), and files concerning the formation of the Ministry of Health (CAB 21/72) and the Ministry of Materials: CAB 21/2271

Separated material:

Some pieces in this class originally contained NATO documents, which were extracted and replaced with dummy cards when the pieces were transferred to the PRO. The dummy cards state that the extracted documents are retained by the Cabinet Office. With the agreement of the PRO, these extracted NATO documents were destroyed by the Cabinet Office in May 2001. Researchers wishing to seek access to extracted documents should apply to the NATO Archives in Brussels.
