The 1929 Battersea South by-election was held on 7 February 1929. The by-election was held when the incumbent Conservative MP, Francis Curzon, succeeded to the peerage as Earl Howe. It was won by the Labour candidate William Bennett in a three-way contest.[1]
The local Liberal association selected 40 year-old Vivian Claude Albu as their candidate. Albu had stood for the Liberals in the 1922 general election at Battersea North.[2] Labour selected William Bennett, who had been their candidate in Guildford in three general elections between 1918 and 1923. The Conservative Party selected Harry Selley, a builder and member of the London County Council for Battersea South.[3]
A few months later at the next general election Bennett again defeated Selley, this time by 418 votes in a much increased poll. The Liberals were again third, though with a new candidate, the former Mayor of Battersea, Captain William J. West.[3] [4] In 1931 Selley won the seat at the third attempt, defeating Bennett with a majority of over 15,000 votes.[4]
