Southwest (Althing constituency)

Southwest (Icelandic: Suðvestur) is one of the six multi-member constituencies of the Althing, the national legislature of Iceland. The constituency was established in 2003 following the re-organisation of constituencies across Iceland when the Reykjanes constituency was split between the new South and Southwest constituencies. Southwest is conterminous with the Capital region but excludes Reykjavík Municipality which has its own constituencies, Reykjavík North and Reykjavík South. The constituency currently elects 12 of the 63 members of the Althing using the open party-list proportional representation electoral system. At the 2024 parliamentary election it had 79,087 registered electors.

History

In September 1997 Prime Minister Davíð Oddsson appointed a committee headed by Friðrik Klemenz Sophusson to review the division of constituencies in Iceland and the organisation of elections. The committee's report was published in October 1998 and recommended, amongst other things, that the number of constituencies be reduced and that they be more equal in population size. The Althing passed an amendment to the constitution in June 1999 which removed the reference to specific eight constituencies contained within Article 31 and instead simply stated that there would be six or seven constituencies and that the Althing would determine the boundaries between the constituencies. The amendment also required that if, following an election to Althing, the number of registered electors per seat (including compensatory seats) in any constituency is less than half of that in another constituency, the National Electoral Commission shall change the allocation of seats so as to reduce the imbalance.

Southwest was one of six constituencies (kjördæmi) established by the "Elections to the Althing Act no.
