It was established by the "Defence (Transfer of Functions) Act 1964," which established the Defence Council and transferred to it the responsibilities and delegated powers of the previous separate departments that managed the armed forces prior to 1964.[3]
The Defence Council consists of the Defence Board, its principal committee, as well as the Admiralty Board, the Army Board and the Air Force Board. The Defence Board is chaired by the secretary of state for defence, the minister of the crown with "general responsibility for defence" of the United Kingdom.[2]
Functions
Prior to 1964, there were five government ministries responsible for the British Armed Forces: the Admiralty, the War Office, the Air Ministry, the Ministry of Aviation, and a smaller Ministry of Defence. By Orders-in-Council issued under the Defence (Transfer of Functions) Act 1964,[4] the functions of these bodies were transferred to the Defence Council and the Secretary of State for Defence, who heads a larger Ministry of Defence.
The Secretary of State for Defence, who is a member of the Cabinet, chairs the Defence Council, and is accountable to the King and to Parliament for its business. The letters patent constituting the Defence Council vest it with the power of command over His Majesty's Forces and give it responsibility for their administration, or in the words of the letters patent:
…to administer such matters pertaining to Our Naval Military and Air Forces as We through Our Principal Secretary of State for Defence direct them to execute And to have command under Us of all Officers Ratings Soldiers and Airmen of Our Naval Military and Air Forces…
In practice, the Defence Council is a formal body, and almost all its work is conducted by the Defence Board. In addition, the three service boards (the Admiralty Board, the Army Board and the Air Force Board), which are sub-committees of the Defence Council meet annually for each service chief to report to the Secretary of State on the health of their respective services.[5]
