By the time of the general election of 1918, the county borough of Hanley had been absorbed into an enlarged county borough of Stoke-on-Trent, and in the boundary changes implemented in that year the same process took place at parliamentary level. The new parliamentary borough of Stoke-on-Trent was accorded three seats in place of the two which the area had had since 1885, and was divided into three single-member constituencies of which Stoke-on-Trent, Hanley was one. The new division was smaller than the old constituency, Burslem now having a seat of its own, and quickly became a safe Labour seat, though the Conservatives won it in their landslide year of 1931.
