Electoral systems in context: United Kingdom

The United Kingdom (UK) is well known for the single-member plurality (SMP) or, more colloquially, the first-past-the-post, electoral system. Devolution of power in the late twentieth century, however, introduced new bodies and positions with new electoral systems, with the total reaching six. These consisted of three majoritarian systems – SMP, block vote, and supplementary vote – as well as three proportional systems – single transferable vote, mixed-member proportional representation, and regional list proportional representation. Sample election results are presented and examined. Despite the presence of several different electoral systems and party systems in the UK with the development of multilevel governance, SMP appears to be entrenched at Westminster, just as SMP systems abroad have, in most cases, also resisted change
