What is the supplementary member electoral system?

The supplementary member electoral system, also known as the parallel voting system, is a mixed electoral system that combines elements of both proportional representation and plurality/majoritarian systems. Under this system, voters have two votes: one for a candidate in a single-member district and another for a political party or a list of candidates in a multi-member district. The single-member district seats are filled using a plurality/majoritarian method, while the multi-member district seats are allocated proportionally based on the party or list vote. This system aims to balance the representation of individual candidates and political parties, providing a mix of direct representation and proportional representation.
