John Alexander Sinclair
From Wikipedia, the free encyclopedia
Sir John Alexander Sinclair, KCMG, CB, OBE (1897–1977) of the British army and head of Military Intelligence. Following his retirement from the military in 1952, as a major-general, he was appointed head of the UK Secret Intelligence Service from 1953 to 1956.
British Prime Minister Anthony Eden forced Sir John Sinclair to resign following a failed frogman mission to investigate the Soviet cruiser Ordkhonikidze that had brought the leader of the Soviet Union Nikita Khrushchev and Prime Minister Nikolai Bulganin on a diplomatic mission to Britain, resulting in the death of frogman Lionel Crabb. The Prime Minister had not approved this mission.
