Elections of Great Britain. There are five types of elections in the United Kingdom

Electoral Register[edit]
Each district council or unitary authority has an Electoral Register which is compiled by the electoral registration officer listing all registered electors. The Electoral Register contains the name, qualifying address and electoral number of every ordinary elector, the name of every special category elector (such as service voters) and the electoral number of every anonymous elector. Any elector who was not aged 18 yet at the time of registration will also have his/her date of birth printed. Each district's Electoral Register is subdivided into separate registers for each polling district.^[33]
Because the franchise differs between individual voters, various markers may be placed next to voters' names to identify in which elections they are entitled to vote.^[34] European Union citizens who are not Commonwealth or Irish citizens have their entry prefixed either with G (meaning they can only vote in local government elections) or K (meaning they can only vote in European Parliamentary and local government elections). Overseas electors are prefixed with the letter F, meaning they can only vote in European and UK Parliamentary elections. Members of the House of Lords residing in the UK are prefixed with the letter L, meaning they can only vote in European Parliamentary and local government elections, whilst peers who are overseas electors are prefixed with the letter E, indicating that they can only vote in European Parliamentary elections.
The register is published every year on 1 December after the annual canvass period^[35] (unless there has been an election during the annual canvass period between 1 July and 1 December,^[35] in which case the publication date is 1 February in the following year^[36]). However, in 2012, because the Police and Crime Commissioner elections were held on 15 November, the annual canvass in England and Wales (excluding London) was held between July and October and the Electoral Register was published on 16 October.^[37] Between January and September, during the 'rolling registration' period, notices of alteration are published on the first working day of each month to add, remove or amend names. Notices of alteration are also published 5 working days before an election at any time of the year^[38] and just before the close of poll at any election to correct any clerical errors or to implement any court decisions.^[39] With the exception of a deceased elector who is removed from the register, any individual who is added or removed from the register must be notified by the electoral registration officer.^[40]
There are two versions of the Register: the full register and the edited register. The full register can only be inspected under supervision at the office of the local electoral registration officer, and must be supplied free of charge to the district's returning officer, the British Library, the Electoral Commission, the Office for National Statistics (only English and Welsh Registers), the General Register Office for Scotland (only Scottish Registers), the National Library of Wales (only English and Welsh Registers), the National Library of Scotland (only English and Scottish Registers) and the relevant Boundary Commission.^[41] The edited register is available for general sale from electoral registration officers and can be used for any purpose.^[42] Electors can choose to opt out from appearing in the edited register by informing their local electoral registration officer.
