Definition:

A mixed member proportional or MMP electoral system usually combines the local representation of a first past the post electoral system with the proportional representation list system to achieve results where the proportion of seats won by a political party comes close to matching the proportion of the total vote for that party.

In a mixed member proportional electoral system, voters usually vote for both a local candidate and for a political party, and the members are elected from single member electoral districts and from party lists.


The Canadian provinces of Ontario, New Brunswick and Quebec are considering the use of a mixed member proportional electoral system for their provincial elections.
