Elections in the United KingdomThere are five types of elections in the United Kingdom: elections to the House of Commons of the United Kingdom (commonly called 'general elections' when all seats are contested), 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.
Semi-proportional representationSemi-proportional representation characterizes multi-winner electoral systems which allow representation of minorities, but are not intended to reflect the strength of the competing political forces in close proportion to the votes they receive. Semi-proportional voting systems can be regarded as compromises between forms of proportional representation such as party-list PR, and plurality/majoritarian systems such as first-past-the-post voting. Examples of semi-proportional systems include the single non-transferable vote, limited voting, and parallel voting.
Majoritarian representationA majoritarian electoral system is an electoral system where the candidate with the most votes takes the seat using the winner-takes-all principle and in this way provides majoritarian representation. However, there are many electoral systems considered majoritarian based on different definitions, including types of at-large majoritarian representation such as block voting or party block voting (general ticket), but district-based majoritarian systems such as first-past-the-post voting (FPTP/SMP).
ScorporoScorporo (ˈskɔrporo, parceling out) is a partially compensatory, mixed-member majoritarian electoral system, sometimes referred to as a negative vote transfer system (NVT) whereby a portion of members are elected in single-member districts (SMDs) and a portion are elected from a list. It may be fully defined as a parallel voting system which excludes a portion (up to 100%) of the SMD winners' votes in electing the proportional tier, to result in a more proportional outcome.
Majority bonus systemThe majority bonus system (MBS) is a form of semi-proportional representation used in some European countries. Its feature is a majority bonus which gives extra seats or representation in an elected body to the party or to the joined parties with the most votes with the aim of providing government stability. It is currently used in Greece, Armenia, San Marino, French Polynesia and formerly in Italy from 2006 to 2013. In Argentina, it is used in the Chamber of Deputies of the Province of Santa Fe, Chubut, and Entre Ríos.
Dual-member proportional representationDual-member proportional representation (DMP), also known as dual-member mixed proportional, is an electoral system designed to produce proportional election results across a region by electing two representatives in each of the region’s districts. The first seat in every district is awarded to the candidate who receives the most votes, similar to first-past-the-post voting (FPTP). The second seat is awarded to one of the remaining district candidates so that proportionality is achieved across the region, using a calculation that aims to award parties their seats in the districts where they had their strongest performances.
