Administrative / biographical background:

Following the establishment of the Ministry of Defence in January 1947 the Joint Intelligence Sub-Committee of the Cabinet became a Ministry of Defence committee in the Chiefs of Staff Sub-Committee committee structure. Its title was amended in January 1948 to Joint Intelligence Committee.

In October 1957 the Prime Minister approved the return of the Joint Intelligence Committee to the Cabinet Office where it remains. It was as a reflection of the broadened scope and role of intelligence that the Joint Intelligence Committee was brought back into the Cabinet Office, as part of the inter-departmental Cabinet Committee structure, under the authority of the Secretary of the Cabinet.
