The 1911 Westbury by-election was a Parliamentary by-election held on 22 February 1911.[1] The constituency returned one Member of Parliament (MP) to the House of Commons of the Parliament of the United Kingdom, elected by the first past the post voting system.
The sitting Liberal Member for Westbury, Sir John Fuller, resigned his seat in the House of Commons on his appointment as Governor of Victoria. He had represented the constituency since 1900, when he gained it from the Conservatives.
On an increased turnout, the Liberal Party held the seat with only a 1.8% swing against them.
A general election was due to take place by the end of 1915, and by the autumn of 1914, the following candidates had been adopted to contest it at Westbury.
However, due to the outbreak of war, there was no general election until 1918. At the 1918 general election, a former Liberal member of parliament, who had joined the Labour Party in 1916, intervened in the contest, handing the seat to the Unionists.
