The Green Party (, or the "Green Environmental Party", commonly referred to in Swedish as "Miljöpartiet" or MP) is a political party in Sweden based upon green politics. The party was founded in 1981, emerging out of a sense of discontent with the existing parties' environmental policies, and sparked by the anti-nuclear power movement following the 1980 nuclear power referendum. The party's breakthrough would come in the 1988 general election when they won seats in the Swedish Riksdag for the first time, capturing 5.5 percent of the vote, and becoming the first new party to enter parliament in seventy years. Three years later, they dropped back below the 4 percent threshold, but returned to parliament again in 1994, and since have retained representation there. The party is represented nationally by two spokespeople, always one man and one woman. These roles are currently held by Gustav Fridolin and Åsa Romson.
