Which electoral system is used in the UK for European Parliamentary elections?

The electoral system used in the UK for European Parliamentary elections is closed list proportional representation. This system allows voters to select a party rather than an individual candidate. Each party presents a list of candidates, and voters choose one party. Seats are then allocated to each party based on the proportion of the total votes they receive, allowing for a more proportional representation of different political beliefs in the European Parliament.

This system aims to ensure that the number of seats a party gains is reflective of the total number of votes they receive, mitigating the winner-takes-all effect seen in some other electoral systems, such as First Past the Post. Closed list proportional representation promotes a wider diversity of representation, including smaller parties that might not receive enough votes to win under a different system.
