Party-list system

A party-list system is a type of electoral system that formally involves political parties in the electoral process, usually to facilitate multi-winner elections. In party-list systems, parties put forward a list of candidates, the party-list who stand for election on one ticket. Voters can usually vote directly for the party-list, but in other systems voters may vote for directly individuals candidates within or across party lists (such systems are referred to as open list and panachage), besides or instead of voting directly for parties (mixed electoral systems).

Most commonly, party-list systems refer to party-list proportional representation, but there are other electoral systems using party-lists including the general ticket (party block voting) and mixed electoral systems. Not only are not all party-list systems proportional, not all proportional systems are party-list systems. Candidates who won their seats from a party-list are called list MPs.
