The Centre Party had been a part of only non-socialist coalition governments from 1930 to 2000, in seven governments, three of which were led by a Prime Minister from the party. By 2005 however, in the 2005 parliamentary election, the party ran for government together with the Labour Party and the Socialist Left Party, as the Red-Green Coalition, with the Centre Party constituting the "green" part of the alliance. The coalition was successful in winning the majority of the seats in the Storting, and negotiations followed with the aim of forming a coalition cabinet led by the Labour Party's leader Jens Stoltenberg.
