When do by-elections happen?
A by-election occurs when a seat in the House of Commons becomes vacant during the lifetime of a Parliament (ie between general elections), because the sitting MP dies, resigns, is elevated to the peerage, or becomes ineligible to sit for some other reason. There have been four by-elections in the current 2017 Parliament.
Further information
The by-elections page of the Parliament website provides detailed information on results, including the number of votes cast and percentage share of the vote.
See the Commons briefing on UK Election Statistics: 1918–2010 for a list of all by-elections in Great Britain and Northern Ireland.
