Dugdale resigned as Attlee's Secretary and enlisted in the Army during the
Second World War and was an Officer. He had edited a book of Attlee's speeches called
The Road to War which was published in 1940. However, when the Labour
Member of Parliament (MP) for
West Bromwich Frederick Roberts resigned due to ill health, Dugdale was chosen to follow him, and he was elected unopposed at the
by-election in April 1941. In December 1941, Dugdale was an organiser of a Labour rebellion in the House of Commons over
National Service. His group put down an amendment insisting that National Service in industry should happen in conjunction with nationalisation of industries involved in the war effort. The Labour whips did not support the amendment. In 1942 he was part of an all-party group which pressed for wider Sunday opening of cinemas and theatres, decrying the campaigning of the
Lord's Day Observance Society. He also took up his interest in China, becoming Secretary of the All-Party Group on China when it was formed in 1943. ==Ministerial Office==
