1950 - 1955
Under the Representation of the People Act 1948 the Boroughs of Hackney and Stoke Newington jointly formed two seats, the borough constituencies of Stoke Newington and Hackney North and Hackney South. Hackney South was enlarged: consisting of the Metropolitan Borough of Hackney except the five wards of Leaside, Maury, Southwold, Springfield and Stamford.
Redistribution
Following a review of constituencies by the Boundary Commission appointed under the House of Commons (Redistribution of Seats) Act 1949, parliamentary seats in the metropolitan boroughs of Bethnal Green, Hackney and Stoke Newington were redrawn. The Hackney South constituency was abolished, with most passing to a new Hackney Central borough constituency, and some parts to Bethnal Green.
