The constituency, officially theBalham and Tooting Division of the Parliamentary Borough of Wandsworth, was created by theRepresentation of the People Act 1918. The 1918 Act had the principal aim of reducing the growingmalapportionment due to electorate growth in geographical areas coupled with the subsidiary aim of realigning constituency boundaries so as to largely correspond with units of local government units (as created in1889 and1900). The new seat was one of five divisions of theMetropolitan Borough of Wandsworth in the parliamentaryCounty of London.[1]
The seat had previously formed part of the single-memberWandsworth constituency, created in1885.[2]
The constituency was defined in terms ofwards of the metropolitan borough as they existed in 1918: it comprised the entireTooting ward and the part of theBalham ward which lay to the west and south of the centre of Balham Hill, Balham High Road, Ormeley Road, Cavendish Road and Emmanuel Road. The remainder of the Balham ward was in another of the Wandsworth divisions,Clapham.[3]
In the redistribution which took effect with the1950 United Kingdom general election the Tooting ward and part of Balham ward were included in the redrawn Wandsworth Central seat. The rest of Balham ward remained in the Clapham constituency.
