Members and their parties
The members of the Riksdag are to ensure that the people's will permeates the Riksdag's decisions. The members who have been voted into the Riksdag and who belong to the same party form a parliamentary party group. In the party groups, the members discuss various matters on which the party is to adopt a position.
Loyalty to the party line is traditionally high at votes in the Riksdag. The underlying idea is that the members are there to implement the programme that was part of the party's election pledge. At the same time, each member of the Riksdag has a personal mandate from the electorate, and is not formally obliged to follow the party line. Acceptance of voting against one's party varies depending on the matter at hand, the party and whether the outcome of the vote is affected.
A member can leave his or her party but remain a member of the Riksdag without a party designation. The party that the member has left then has one seat fewer. However, the total number of seats in the Riksdag is not affected, nor is the number of seats for any other party.
A member who leaves his or her party group thus also leaves assignments in committees and other Riksdag bodies, for example Riksdag boards, to which the member has been elected by the Chamber.
Debate and decide
It is in the Chamber that the members of the Riksdag debate important matters and take decisions. Before the Riksdag takes a decision on an item of parliamentary business, the members often debate the matter in the Chamber. The members also participate in other kinds of debate, such as interpellation debates and current affairs debates.
