The 1946 Hemsworth by-election was a parliamentary by-election held in England for the British House of Commons constituency of Hemsworth on 22 February 1946.
The Labour candidate, Horace Holmes, was returned unopposed.
[1] This was the last uncontested Parliamentary election to date outside Northern Ireland.
During World War II, unopposed by-elections were common, since the major parties had agreed not to contest by-elections when vacancies arose in seats held by the other parties; contests occurred only when independent candidates or minor parties chose to stand, and the Common Wealth Party was formed with the specific aim of contesting war-time by-elections.
This may have been a factor in the lack of a Conservative candidate at the by-election.
