The Wandsworth by-election was a Parliamentary by-election. It returned one Member of Parliament to the House of Commons of the United Kingdom, elected by the first past the post voting system.
At the 1885 general election, Sir Henry Kimber was elected as the Member of Parliament (MP) for Wandsworth. He held the seat until his resignation in June 1913, by taking the Chiltern Hundreds.
Samuel Samuel was chosen by the Unionists to defend the seat. He unsuccessfully contested Leeds West at the 1906 and January 1910 general elections, and was unsuccessful again in Sunderland at the December 1910 general election.
Joseph Havelock Wilson was chosen by the local Liberals as their candidate. He was MP for Middlesbrough from 1892 to 1900 and again from 1906 to 1910. He was President of the National Sailors' and Firemen's Union.
