Joint Intelligence Committee

The Joint Intelligence Committee (JIC) is part of the British Cabinet Office. It supervises the intelligence organisations of the United Kingdom on behalf of the Cabinet. More generally, it gives advice to the Cabinet on security, defence and foreign affairs.
The JIC sets priorities for the intelligence and security agencies: MI6, MI5, GCHQ, and Defence Intelligence.
Structure.
The Committee is chaired by a permanent chairman, a member of the senior Civil Service, who is supported by the Intelligence and Security Secretariat and an assessment staff. The assessment staff is made up of experienced senior analysts drawn from across government and the military and conducts all-source analysis on subjects of interest to the committee. JIC papers written by the staff draw input from across the intelligence and security agencies and other related bodies.
Membership is the heads of the three collection agencies—the Secret Intelligence Service, Security Service and GCHQ—the Chief of Defence Intelligence, Deputy Chief of Defence Intelligence Staff, the Chief of the Assessment Staff, representatives of the Ministry of Defence, Foreign and Commonwealth Office and other departments, and the Prime Minister's adviser on foreign affairs.

History.
The JIC was founded in 1936 as a sub-committee of the Committee of Imperial Defence. This was the advisory defence planning agencyat the time. During World War II, it became the senior intelligence assessment body in the UK. In 1957 the JIC moved to the Cabinet Office. Its assessments staff prepare draft intelligence assessments for the Prime Minister and the Cabinet.
The JIC is monitored by the Intelligence and Security Committee of Parliament and supported by the Joint Intelligence Organisation.
Foreign involvement.
Ever since World War II, the chief of the London station of the United States Central Intelligence Agency has attended the JIC's weekly meetings. One former US intelligence officer has described this as the "highlight of the job" for the London CIA chief. Resident intelligence chiefs from Australia, Canada, and New Zealand may attend when certain issues are discussed.
