Crozier provided advice to the British Secret Intelligence Service, to the Information Research Department (IRD) of the British Foreign Office, and to the CIA. Lecturing to Britain's staff college for army officers during the early 1970s, when the Labour Party was in power under Harold Wilson, Crozier stated if the government went "too far", it was the armed forces' duty to intervene (he claimed that he was enthusiastically applauded). In 1982, it was revealed from the papers of a former Bavarian state security chief, Hans Langemann, that Crozier was an attendant of Le Cercle and headed a secret international group that tried to influence the West German federal election of 1980 by using secret-service connections and cover-up financial transactions to make Franz Josef Strauß Chancellor of the Federal Republic of Germany. Crozier was a co-founder of the group The 61, an organisation that wanted to counter Soviet communist propaganda. HarperCollins published Crozier's autobiography, Free Agent: The Unseen War 1941–1991, in 1993, which was revised and corrected in paperback edition in 1994.
