A
general election was held in
Sweden on 17 September 2006, to elect members to the
Riksdag, the Swedish national legislature. All 349 seats were up for election: 310 fixed seats in 29
constituencies and 39 adjustment seats, used to ensure that parties have representation in the Riksdag proportional to their share of the national vote. The electoral system used was
semi-open list proportional representation using the
Sainte-Laguë method of allocating seats. Elections for
County and
Municipal councils were also held on the same day.
