Movimiento de Izquierda-Verde
Five parties were elected at the previous election, held in April 2009. Since then, the parliamentary representation for one of these, Citizens' Movement, first mostly moved to The Movement and then, in March 2012, to the new party Dawn. One of the MPs elected for the Citizens' movement, Þráinn Bertelsson, left the parliamentary party almost immediately and then a 16 months after the 2009 election he joined the Left-green movement. In January 2012, the new party Solidarity was founded by an incumbent MP, Lilja Mósesdóttir, who was elected as a member of the Left-Green Movement. Another new party, Bright Future, was formed in February 2012 with the involvement of two MPs from, respectively, the Progressive Party and Social Democratic Alliance. One MP originally elected for Citizens' Movement, Birgitta Jónsdóttir, also participated in the establishment of a new party in 2012, namely the Pirate Party. Two eurosceptic Left-Green Movement MPs, Jón Bjarnason and Atli Gíslason, also decided to defect and form the new Rainbow Movement in March 2013. The box below shows the distribution of seats in the incumbent parliament on 28 March 2013, the last working day of the parliament's term.
