The non-socialist parties retained a reduced majority of 88 seats, allowing Prime Minister Erna Solberg's Conservative-Progress coalition to remain in government.

A modification of the Sainte-Lague method, where the first quotient for each party is calculated using a divisor of 1.4 instead of 1, is used to allocate both the constituency and leveling seats.

The Norwegian parliament may not be dissolved before such a four-year term has ended, a rather rare trait of a political system found in few, if any democracies besides Norway and the USA.

Additionally, the far-left Red Party led by Bjørnar Moxnes secured its first seat via a direct mandate in Oslo district.

The party is officially Communist in orientation and is a successor to the Red Electoral Alliance, which had previously won a seat in the 1993 election.

In late September 2017, the Christian Democrats left coalition talks due to the inclusion of the Progress Party.

[28][29] On 20 January 2020, the Progress Party decided to withdraw from the government due to a decision by Solberg to repatriate a woman linked to Islamic State and her children back to Norway.
