Icelanders cast ballots in the country's second parliamentary election in just a year on Saturday after a "breach of trust" within the center-right coalition forced the government to collapse and prompted the snap vote.
Voting began at 9 a.m. local time (0900 GMT) and is due to close at 10 p.m. (2200 GMT). First results are expected to be announced shortly thereafter and final vote count is expected on the morning of Sunday.
A poll published Friday showed that Iceland's center-right coalition government was set to loose its majority in parliament on the general election, online newspaper Iceland Monitor reported.
Two left-of-center opposition parties, the Social Democratic Alliance and the Left-Green Movement, are expected to gain seats but fall short to form a majority government, the poll said.
According to the poll, the Independence Party leads with 24.5 percent of votes, but a two-party coalition is not possible. A three party coalition would only be an option with the right-of-center Independence Party on board.
A center-left government with the Left-Green Movement and the Social Democratic Alliance would need two other parties to form a majority government, the poll showed.
Last month Prime Minister Bjarni Benediktsson of the Independence Party called for a new parliamentary election after Bright Future, a junior partner in the three-party governing coalition, decided to quit due to a "breach of trust" within the government.
Bright Future's move effectively led to the collapse of Iceland's government as the three-party ruling coalition holds a slim majority with 32 seats in the 63-seat parliament. The Reform Party, another junior partner, also called for new elections as soon as possible.
It followed the revelation that Benediktsson's father signed a letter of recommendation so that a convicted pedophile would receive what in Iceland is called "restored honor," which effectively wipes the criminal record of a person who has served his or her sentence.
The center-right coalition government only took office in January after the last parliamentary election on Oct. 29, 2016.
Last year's election was prompted by the resignation of Iceland's then prime minister Sigmundur David Gunnlaugsson in April after the so-called Panama Papers suggested Gunnlaugsson and other two cabinet members had ties with offshore companies.
