National apportionment of MP seats in the Riksdag: The electoral system in Sweden is proportional.  Of the 349 seats in the national diet, the unicameral "Riksdag", 310 are fixed constituency seats (Swedish: "valkretsmandat" ) allocated to constituencies in relation to the number of people entitled to vote in each constituency (Swedish: "valkrets" ).  The remaining 39 leveling seats (Swedish: "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.
