The party was established on 24 September 2020 by former county leaders from the Christian Democratic Party (KrF) and former Oslo city councilor Geir Lippestad of the Labour Party. The KrF county leaders left their party after an internal split between the KrF's left and right factions, in which the latter won. Lippestad led the initiative to form the party and was elected its inaugural leader at the party's founding congress.[1][2] The party later received further defectors from the Labour Party, the Socialist Left Party, the Conservative Party, and the Green Party.[3][4]
In December 2020, the party secured enough signatures to run lists in all counties for the 2021 parliamentary election.[5] It officially registered as a political party in January 2021.[1]
Partiet Sentrum was measured in opinion polls in the winter of 2020–2021 between 0.0 and 0.7 per cent support.[6][7] In the spring of 2021, Norstat conducted a nationwide survey commissioned by the Center Party, to answer how the party fared before the parliamentary elections in 2021.[8] Two percent of the 1,000 respondents answered "yes" to the question of whether they considered voting for the party in the autumn elections. Nine percent answered "maybe", and 13% answered "do not know".[9]
The 2021 parliamentary election was held on 13 September. The party received 0.3% of the popular vote in the election and no seats in the Storting.[10] After the election, the party advocated a change in government.[11]
