 In July 1943 Dunglass attended the House of Commons for the first time since 1940 , and began to make a reputation as a backbench member , particularly for his expertise in the field of foreign affairs . He foresaw a post @-@ imperial future for Britain and emphasised the need for strong European ties after the war . In 1944 , with the war now turning in the Allies ' favour , Dunglass spoke eloquently about the importance of resisting the Soviet Union 's ambition to dominate eastern Europe . His boldness in publicly urging Churchill not to give in to Joseph Stalin was widely remarked upon ; many , including Churchill himself , observed that some of those once associated with appeasement were determined that it should not be repeated in the face of Russian aggression . Labour left the wartime coalition in May 1945 and Churchill formed a caretaker Conservative government , pending a general election in July . Dunglass was appointed to his first ministerial post : Anthony Eden remained in charge of the Foreign Office , and Dunglass was appointed as one of his two Under @-@ secretaries of State .
