The parliament in Liechtenstein is known as the "Landtag". Together with the Prince, the 25 Members of Parliament form the country's legislative authority. The parliament, representing the people, and the Princely House, represented by the Prince, are the legislative bodies in Liechtenstein. If they are unable to agree on a matter a referendum is called.
The parliament, which comprises 25 members, is elected every four years by the people. Liechtenstein is divided into two constituencies: the Oberland and the Unterland. Laws passed by parliament must be approved by the Prince, countersigned by the Prime Minister and published in the National Legal Gazette. Laws that are not approved by the Prince within six months do not enter into force and are considered as having been rejected by the Prince.
There are two long-standing political parties (Progressive Citizens' Party and Patriotic Union) and three opposition parties (Free List, The Independents and democrats pro Liechtenstein) competing for the 25 seats in parliament. Since its creation in 1985, the Free List has been a constant political presence in Liechtenstein and gained its first seats in parliament in 1993. The Independents won in 2013 four seats in parliament during their first elections. A fifth party, the democrats pro Liechtenstein were founded in 2018.
Until around 20 years ago political allegiances were more or less "passed on" down through the generations: certain families voted left, others right. However, this has changed in recent years. Today, many voters base their decisions on the merits of the respective parties.
