General Election 1939–40: Another General Election was required to take place before the end of 1940. The political parties had been making preparations for an election to take place from 1939 and by the end of this year, the following candidates had been selected;

• Conservative: Joseph Leech
• Labour: Henry Hird

At the outbreak of the Second World War the planned election was postponed and the major parties agreed to an electoral truce, where they would not contest by-elections against each other for the duration of the war.^[9] This meant that following Joseph Leech's death in May 1940 neither Labour nor the Liberal Party stood candidates, and the Conservative candidate was unopposed.
