United Kingdom by-election records

UK by-election records is an annotated list of notable records from UK Parliamentary by-elections
UK Parliamentary by-elections
Parliamentary by-elections in the United Kingdom occur following a vacancy arising in the House of Commons. They are often seen as a test of the rival political parties' fortunes between general elections.-Resignations:...

. A by-election occurs when a Member of Parliament
Member of Parliament
A Member of Parliament is a representative of the voters to a :parliament. In many countries with bicameral parliaments, the term applies specifically to members of the lower house, as upper houses often have a different title, such as senate, and thus also have different titles for its members,...

 resigns, dies, or is disqualified or expelled, and an election is held to fill the vacant seat. A constituency is the seat or division that member represented.

Prior to 1945, electoral competition in the United Kingdom exhibited features which make meaningful comparisons with modern results difficult.

Among the most significant were:
  • Frequent interventions and withdrawals of parties in different seats.
  • Frequent Coalitions between parties, splits within parties and floor-crossing by members.
  • Uncontested elections and truces between parties, in particular during both World Wars.
  • Generally more significant competition from independent candidates and minor parties.
  • Multi-member seats and University seats.
  • Higher frequency of by-elections.
  • Generally higher turnouts, although several wartime elections exhibited the lowest recorded turnouts.
  • Generally higher variation in size of constituency electorates.


Since 1945, the evolution of a stable three-party system has tended to negate each of the above features so that, broadly speaking, elections are more comparable.

, as ever, the pattern of party competition is completely different from that on the mainland and comparisons remain problematic.

Hence, unless otherwise stated records are based on results since the 1945 General Election, and earlier exceptional results are listed separately.

For comparison purposes the following definitions have been adopted.
  • Gain - victory by a party which was not victorious at the immediate previous election.
  • Loss - defeat of a party which was victorious at the immediate previous election.
  • Hold - victory by a party which was victorious at the immediate previous election.
  • Win - victory by a party. Ambiguous term that could mean either a gain or a hold.
  • Incumbent - the party which held the seat at the immediate previous election, irrespective of any intervening change of candidate or candidate's change of party.
  • Third party - In England, since 1922
