national apportionment of MP seats in the Riksdag

{{Politics of Sweden|riksdag}}

The electoral system in Sweden is proportional. Of the 349 seats in the national diet, the unicameral Riksdag, 310 are fixed constituency seats ({{langx|sv|valkretsmandat}}) allocated to constituencies in relation to the number of people entitled to vote in each constituency ({{lang|sv|valkrets}}). The remaining 39 leveling seats ({{lang|sv|utjämningsmandat}}) are used to correct the deviations from proportional national distribution that may arise when allocating the fixed constituency seats. There is a constraint in the system that means that only a party that has received at least four per cent of the votes in the whole country participates in the distribution of seats. However, a party that has received at least twelve per cent of the votes in a constituency participates in the distribution of the fixed constituency seats in that constituency.See e.g.: [http://www.regeringen.se/sb/d/10025/a/117744 SOU 2008:125 En reformerad grundlag (Constitutional Reform)], Prime Ministers Office.For the general election of 2010, See e.g.: [http://allehanda.se/start/harnosand/1.861758 Länet tappar ett mandat], Örnsköldsviks Allehanda, March 20, 2009.
