Catalogue description War Cabinet: Joint Intelligence Committee, Inter-Services Security Board: Minutes

The Inter-Services Security Board was initially set up in February 1940 in connection with projected operations in Finland and was established in March 1940 as a permanent body for the duration of the War. It was responsible under the direction of the Joint Intelligence Committee for the co-ordination of all security measures in connection with the British war effort. Later it also became responsible for the co-ordination and control of code names. The organisation of deception schemes was part of the board's brief until 1941 when the task was largely transferred to a special section within the War Cabinet.
