In January 1936, the Committee of Imperial Defence created the Inter-Service Intelligence Committee, which by July of that year evolved into the Joint Intelligence Sub-Committee.

Between July 1936 and August 1939, the JIC was composed of the deputy directors of intelligence of the three services, frequently with a representative from the Industrial Intelligence Centre and, from November 1938, with representation from the Foreign Office. Whilst the JIC had inherited from the Inter-Service Intelligence Committee the remit which included the preparation of reports, as well as the co-ordination on the work of the three services, in practice the Sub-Committee acted in a reactive capacity, responding to specific requests for information from the Chiefs of Staff, the Joint Planners or the individual service departments.

On the outbreak of war in September 1939, the Committee of Imperial Defence was dissolved, but the Joint Intelligence Sub-Committee continued in being as one of the principal subordinate bodies of the Chiefs of Staff Committee.
