As of 2019, the House consists of 650 members; this total includes the Speaker, who by convention renounces partisan affiliation and does not take part in debates or votes, as well as three Deputy Speakers, who also do not participate in debates or votes but formally retain their party membership. Each Member of Parliament (MP) is chosen by a single constituency by the First-Past-the-Post electoral system. There are 650 constituencies in the United Kingdom, each made up of an average of 65,925 voters. The First-Past-the-Post system means that every constituency elects one MP each (except the constituency of the Speaker, whose seat is uncontested). Each voter assigns one vote for one candidate, and the candidate with the most votes in each constituency is elected as MP to represent their constituency. Members sit for a maximum of five years, although elections are generally called before that maximum limit is reached.
