 During the early period of Gaitskell's tenure as Party Leader, the opposition between the Gaitskellites and Bevanites simmered, centering mainly on the issues of nuclear disarmament (which the Bevanites supported and the Gaitskellites opposed) and Britain's participation in NATO, specifically the foreign policy of opposing the Soviet Union and supporting the United States (which the Bevanites opposed and Gaitskellites supported).However, during this initial period the factional infighting dimmed somewhat; Gaitskell appointed Bevan to the Shadow Cabinet as Shadow Colonial Secretary and then Shadow Foreign Minister, the position he held during the Suez Crisis which enabled him to formulate Labour's response to the actions of Prime Minister Anthony Eden.Also in 1956, Bevan was elected Party Treasurer, defeating the Gaitskellite candidate, George Brown.
