Since a party group must consist of at least four members and represent at least two countries there are some members who are not affiliated with any of the registered party groups. The Nordic Council's governing body, the Presidium, sets the rules for the registration of party groups.
The party groups in the Nordic Council get party support for their activities. Unaffiliated members, or members who have previously been registered to a party group, can certainly receive support.
Currently there are five political party groups in the Nordic Council; the Left-wing Socialist Green group, the Social Democratic group, the Centre group, the Conservative group and Nordic Freedom.
These party groups have their own party group secretariat and secretary.
