Additional Member System

The Additional Member System (AMS) is a branch of voting systems in which some representatives are elected from geographic constituencies and others are elected under proportional representation from party lists. Voters have two votes, one for the party and the second for the candidate in a constituency. The constituency representatives are generally elected under the first-past-the-post voting system. The party list representatives are elected by a second vote, where the electors vote for a political party, not directly for an individual. The particular individuals selected come from lists drawn up by the political parties before the election, at a national or regional level.

Additional Member System er et valgsystem der velgerne har to stemmer hver, og disse brukes til å velge representanter gjennom ulike valgsystemer. Som regel har velgerne i denne typen systemer én stemme i et forholdstallsvalg og én stemme i et flertallsvalg. Denne ordningen er ment å sikre både stabilitet, som er et typisk trekk ved flertallsvalg, og samtidig også sørge for at mindre partier blir representert.
