List MPs

A list MP is a Member of Parliament (MP) who is elected from a party list rather than from a geographical constituency. Their presence in Parliament is owed to the number of votes that their party won, not to votes received by the MP personally. This occurs only in countries which have an electoral system based on party-list proportional representation.

In some countries, seats in the chamber are filled solely in accordance with the share of votes won by each individual party. Thus, in Israel, all Members of the Knesset (MKs) are list members. Under this system, MKs are appointed from lists of candidates created by each party until the party has reached its allocated number. In other countries, a more complicated system is used. In the method used in Russia and Japan, some seats are filled using party lists, while others are filled by the "traditional" First Past the Post system. Under the Additional Member System, or Mixed Member Proportional, the method used in Germany and New Zealand, a merger of party-list representation and geographic representation is employed — parties contest geographic seats, but are then "topped up" with MPs from a party list. New Zealand has 120 MPs represented by 5 parliamentary parties, out of which there are 64 general electorate seats and seven Māori electorates, elected using First Past the Post voting system (FPP). the candidate who gets the most votes wins. The other 49 MPs are selected from the party lists . The List MPs each party gets is the difference between a party’s total allocation of seats in parliament and its number of electorate MPs.

The existence of list MPs has caused controversy in some countries. It is sometimes complained that because list MPs do not have a geographic electorate, they are not properly accountable to anyone. In addition, the methods used to create party lists are sometimes criticised as undemocratic — in a closed list system, the public have no way of influencing the composition of a party list. In this situation, the public cannot support one candidate without also supporting other candidates from the same party. (Supporters of party list proportional representation sometimes retort that the public often have little control over the selection of local candidates, either — if a voter's preferred party selects a poor candidate, the voter is forced to either vote for a candidate they dislike or vote for a party they dislike. Under a party list system, voters can support their preferred party even if they are unwilling to vote for its local candidate.) An open list system, however, may go some way to addressing this concern.
