UK parliamentary by-elections
UK Parliamentary by-elections are run when a seat in the House of Commons becomes vacant. This can happen when a sitting member of the UK parliament (MP):
- resigns or dies
- is declared bankrupt
- takes a seat in the House of Lords
- is convicted of a serious criminal offence
- loses a seat as a result of recall petition
The administration of a by-election is the responsibility of the (Acting) Returning Officer (or the Returning Officer in Scotland). Details on the delivery of a specific by-election should be directed to the relevant local authority or council.
