The First cabinet of Katrín Jakobsdóttir was formed on 30 November 2017, following the 2017 parliamentary election. The cabinet was led by Katrín Jakobsdóttir of the Left-Green Movement, who served as Prime Minister of Iceland.
The cabinet was a coalition government consisting the Independence Party, the Left-Green Movement and the Progressive Party.[1] Together they held 33 of the 63 seats in the Parliament of Iceland (i.e. Althing; Icelandic: Alþingi) and served as a majority government. In the cabinet, there were eleven ministers, where five were from the Independence Party, three were from the Left-Green Movement and three were from the Progressive Party.[2] After the election in 2017 the parties had 35 seats in the parliament, but since then two MPs have left the Left-Green Movement.[3] [4]
