The number of MPs fell from 707 to 620 because 78 territorial seats and three university seats in Ireland were lost because of the creation of the Irish Free States. In Northern Ireland, six seats were abolished: Antrim Mid, Armagh Mid, Down Mid, and three in Belfast: Cromac, Pottinger, and St. Anne's. The city still elected six MPs.

Sir Oswald Mosley had been elected as an Independent for Harrow in the 1923 general election. In May 1924 he joined the Labour Party. Harrow would never elect a Labour MP, so he stood in the most marginal Conservative seat in Birmingham, which was King's Norton, in the south of the city, which had a Conservative majority of 3.7%. His wife, Lady Cynthia Mosley, campaigned with him. He was elected with a majority of 7.1%. Herbert Morrison gained Hackney South for Labour from Liberal, but Hugh Dalton lost Holland-with-Boston to Liberal. Harold Macmillan failed to be elected as Conservative MP for the Liberal seat of Stockton-on-Tees.
