Left-Green Movement in the context of Ásmundur Einar Daðason

Snap parliamentary elections were held in Iceland on 25 April 2009, following strong pressure from the public as a result of the Icelandic financial crisis. The Social Democratic Alliance and the Left-Green Movement, which formed the outgoing coalition government under Prime Minister Jóhanna Sigurðardóttir, both made gains and formed an overall majority of seats in the Althing. The Progressive Party also made gains, and the new Citizens' Movement, formed after the January 2009 protests, won four seats. The big loser was the Independence Party, which had been in power for 18 years until January 2009; it lost nine seats as its vote share was reduced by around a third, meaning it was not the most voted-for party for the first time since 1937

Early parliamentary elections were held in Iceland on 28 October 2017. On 15 September 2017, the three-party coalition government collapsed after the departure of Bright Future over a scandal involving Prime Minister Bjarni Benediktsson's father writing a letter recommending a convicted child sex offender have his "honour restored". Bjarni subsequently called for a snap election, which was officially scheduled for 28 October 2017 following the dissolution of the Althing.

Though many opinion polls in the run-up to the election indicated an increase in support for the Left-Green Movement, the Independence Party retained its position as the Althing's largest party. Following the election, four-party coalition talks led by the Left-Greens ensued; however, after the Progressive Party rejected the possibility, a three-party coalition led by the Left-Greens including the Independence Party and Progressive Party was negotiated. After formally receiving the mandate to form a coalition on 28 November, Left-Green leader Katrín Jakobsdóttir was designated Prime Minister to lead the new government on 30 November.
