Greater London is divided into fourteen territorial constituencies for London Assembly elections, each returning one member. The electoral system used is additional member system without an overhang and there are, therefore, a fixed number of eleven additional members elected from a party list.
As of the 2016 election, the fourteen single-member constituencies are listed below. As set out in the Greater London Authority Act 1999, each constituency comprises between two and four local authorities, with an average electorate of around 440,000. The total electorate in 2021 was 6,191,387. [1]

Proportional representation (PR) refers to any type of electoral system under which subgroups of an electorate are reflected proportionately in the elected body. The concept applies mainly to political divisions among voters. The essence of such systems is that all votes cast – or almost all votes cast – contribute to the result and are effectively used to help elect someone. Under other election systems, a bare plurality or a scant majority are all that are used to elect candidates. Further, a PR system is one that produces mixed and balanced representation, reflecting how votes are cast.
Elections in Sweden are held once every four years. At the highest level, all 349 members of Riksdag, the national parliament of Sweden, are elected in general elections. Elections to the 20 county councils and 290 municipal assemblies – all using almost the same electoral system – are held concurrently with the legislative elections on the second Sunday in September.
The additional-member system (AMS) or is a mixed electoral system under which most representatives are elected in single-member districts (SMDs), and a fixed number of other "additional members" are elected to make the seat distribution in the chamber more proportional to the way votes are cast for party lists. It is distinct from parallel voting in that the "additional member" seats are awarded to parties taking into account seats won in SMDs, which is not done under parallel voting.
Mixed-member proportional representation is a mixed electoral system which combines local winner-take-all elections with a compensatory tier of party list votes, which are used to allocate additional members in a way that aims to produce proportional representation overall. In typical MMP systems, voters get two votes: one to decide the representative for their single-seat constituency, and one for a political party. Some countries use single vote variants of MMP, although this article focuses primarily on dual vote versions of MMP.
In the United Kingdom, the boundary commissions are non-departmental public bodies responsible for determining the boundaries of parliamentary constituencies for elections to the House of Commons. There are four boundary commissions: one each for England, Scotland, Wales and Northern Ireland.
The London Assembly is a 25-member elected body, part of the Greater London Authority, that scrutinises the activities of the Mayor of London and has the power, with a two-thirds supermajority, to amend the Mayor's annual budget and to reject the Mayor's draft statutory strategies. The London Assembly was established in 2000. It is also able to investigate other issues of importance to Londoners, publish its findings and recommendations, and make proposals to the Mayor.
In political science, parallelvoting or superposition refers to the use of two or more electoral systems to elect different members of a legislature. More precisely, an electoral system is a superposition if it is a mixture of at least two tiers, which do not interact with each other in any way; one part of a legislature is elected using one method, while another part is elected using a different method, with all voters participating in both. Thus, the final results can be found by calculating the results for each system separately based on the votes alone, then adding them together. A system is called fusion or majority bonus, another independent mixture of two system but without two tiers. Superposition is also not the same as "coexistence", which when different districts in the same election use different systems. Superposition, fusion and coexistence are distinct from dependent mixed electoral systems like compensatory (corrective) and conditional systems.
An electoraldistrict, sometimes called a constituency, riding, or ward, is a subdivision of a larger state created to provide its population with representation in the larger state's legislature. That body, or the state's constitution or a body established for that purpose, determines each district's boundaries and whether each will be represented by a single member or multiple members. Generally, only voters (constituents) who reside within the district are permitted to vote in an election held there. District representatives may be elected by a first-past-the-post system, a proportional representative system, or another voting method. They may be selected by a direct election under universal suffrage, an indirect election, or another form of suffrage.
In the United Kingdom (UK), each of the electoral areas or divisions called constituencies elects one member to the House of Commons.
The Senedd constituencies and electoral regions are the electoral districts used to elect members of the Senedd to the Senedd, and have been used in some form since the first election of the then National Assembly for Wales in 1999. New boundaries were introduced for the 2007 elections and currently consist of forty constituencies and five regions. The five electoral regions are: Mid and West Wales, North Wales, South Wales Central, South Wales East, and South Wales West, with the forty constituencies listed below. Voting last took place in all districts in the 2021 Senedd election, and is not used for local government.

Also, however, it is one of eight constituencies in the Mid and West Wales electoral region, which elects four additional members, in addition to eight constituency members, to produce a degree of proportional representation for the region as a whole. It is currently represented by James Evans MS, of the Conservatives who has been the MS since May 2021.

Electoral districts go by different names depending on the country and the office being elected.
In an electoral system, a deposit is the sum of money that a candidate for an elected office, such as a seat in a legislature, is required to pay to an electoral authority before they are permitted to stand for election.
There are five types of elections in the United Kingdom: elections to the House of Commons of the United Kingdom, elections to devolved parliaments and assemblies, local elections, mayoral elections, and police and crime commissioner elections. Within each of those categories, there may also be by-elections. Elections are held on Election Day, which is conventionally a Thursday, and under the provisions of the Dissolution and Calling of Parliament Act 2022 the timing of general elections can be held at the discretion of the prime minister during any five-year period. All other types of elections are held after fixed periods, though early elections to the devolved assemblies and parliaments can occur in certain situations. The five electoral systems used are: the single member plurality system (first-past-the-post), the multi-member plurality, the single transferable vote, the additional member system, and the supplementary vote.
The London Assembly election of 2012 was an election of members to the London Assembly which took place on Thursday, 3 May 2012, the same day as the 2012 London mayoral election, and the 2012 United Kingdom local elections. Although Conservative candidate Boris Johnson won the Mayoral election, the Assembly election produced the Labour Party's best result since the inception of the London Assembly; this was subsequently surpassed by the party's performance in the 2016 election.
