The Althing is the national parliament of which country?

The Alþingi (parliament (Icelandic) and anglicised as Althingi or Althing) is the national parliament of Iceland. It is one of the oldest parliaments in the world. The Althing was founded in 930 at Þingvellir ("thing fields"), situated approximately 45 kilometres (28 mi) east of what later became the country's capital, Reykjavík. In 1844 it was moved to Reykjavík, where it has resided ever since. The parliament building, the Alþingishús, was built in 1881, of hewn Icelandic stone.

The unicameral parliament has 63 members, and is elected every four years based on party-list proportional representation.

The constitution of Iceland provides for six electoral constituencies with the possibility of an increase to seven. The constituency boundaries and the number of seats allocated to each constituency are fixed by legislation. No constituency can be represented by fewer than six seats. Furthermore, each party with more than 5% of the national vote is allocated seats based on its proportion of the national vote in order that the number of members in parliament for each political party should be more or less proportional to its overall electoral support. If the number of voters represented by each member of Alþingi in one constituency would be less than half of the comparable ratio in another constituency, the Icelandic National Electoral Commission is tasked with altering the allocation of seats to reduce that difference.
