1885–1918 In 1885 the constituency was defined as consisting of: • No. 7 or South Hackney
Ward of Hackney Parish • No. 6 or
Homerton Ward of Hackney Parish • The part of the No. 5 or Hackney Ward of Hackney Parish south of the centres of Everning Road, Upper Clapton Road, and the Upper and Lower Clapton Roads.
1918–1950 The
Representation of the People Act 1918 redrew constituencies throughout
Great Britain and Ireland. Seats in the
County of London were redefined in terms of wards of the
Metropolitan Boroughs that had been created in
1900. The
Metropolitan Borough of Hackney was divided into three divisions, with the same names as the constituencies created in 1885. Hackney South was defined as consisting of: • Homerton Ward • South Hackney Ward • The part of Clapton Park Ward to the south of a line drawn along the centres of Glenarm Road, Glyn Road and Redwald Road to its junction with Maclaren Street, thence across the recreation grounds in Daubeney Road to the borough boundary at a point fifty feet north of a boundary post situate at the junction of the Waterworks River with the River Lea at Lead Mill Point.
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. ==Members of Parliament==
