Riksdag members of the Riksdag are elected in the general elections held every four years. All Swedish citizens who turn 18 years old no later than on the day of the election are eligible to vote in and stand for elections. A minimum of 4% of the national vote is required for a party to enter the Riksdag, alternatively 12% or more within a constituency. Substitutes for each deputy are elected at the same time as each election, so by-elections are rare. In the event of a snap election, the newly elected members merely serve the remainder of the four-year term.
