 As the borough of Southwark had only 67,279 electors on 15 October 1946, the relevant date for the subsequent Boundary Commission review, the borough was only entitled to a single Member of Parliament.As a consequence Southwark Central was abolished as a separate constituency by the Representation of the People Act 1948, along with its neighbours Southwark North and Southwark South East and went out of existence at the 1950 general election, forming part of the re-established Southwark constituency.When the constituency was created, it was defined to include three whole wards of the Metropolitan Borough of Southwark (St Mary's, St Paul's and Trinity) together with a small section of the St George's ward.
