Major parties The
Social Democratic Party (S;
Socialdemokraterna) was the largest political party in the Swedish
Riksdag, with 113 of the 349 seats. It was the major component of the incumbent
Löfven Cabinet, in which it worked with the
Green Party. Its
leader Stefan Löfven had been
Prime Minister of Sweden since 3 October 2014, and sought a mandate to continue his Löfven Cabinet. The
Moderate Party (M;
Moderaterna) was the second-largest party in the Riksdag with 84 seats. It was the largest governing party under
Prime Minister Fredrik Reinfeldt from 2006 to 2014. The party was involved alongside three other parties in the
Alliance; all four sought to return to power together. Reinfeldt resigned as party leader after eight years as prime minister, and was succeeded as leader by
Anna Kinberg Batra on 10 January 2015. Kinberg Batra's decision as the
de facto leader to enter the budgetary procedure agreement with the left-of-centre cabinet saw sharp disgruntlement from some party districts. The Alliance had more MPs than the government parties, but still found itself in opposition. Owing to her low
opinion polling numbers, Kinberg Batra faced internal pressure from multiple party districts and the
Moderate Youth League to resign. She announced her resignation in a morning press conference on 25 August 2017. Former prime minister and Moderate Party leader
Carl Bildt was suggested as a replacement after Kinberg Batra resigned; however, despite some party districts supporting his candidacy, he declined the offer. Ultimately, Ulf Kristersson was elected to succeed Kinberg Batra as party leader, during an extra Moderate
party conference on 1 October 2017. The
Sweden Democrats (SD;
Sverigedemokraterna) was the third-largest party in the Riksdag with 49 seats. In the
2014 general election the party increased its number of seats by 29, becoming the third-largest party. Its leader was
Jimmie Åkesson, who was the longest-serving party leader. The other Riksdag parties had repeatedly stated that they would not cooperate with the Sweden Democrats in a future government. An extra general election was called after the Sweden Democrats gave its support to the oppositional Alliance budget (see section '2014 budget crisis'). After the proposed extra election was cancelled, the party advertised itself as the 'only opposition party' and in the following months it saw a sharp rise in support (see section 'Opinion polls'). The
Green Party (MP;
Miljöpartiet) was the fourth-largest party in the Riksdag with 25 seats. The Green Party was the minor component of the Löfven Cabinet, alongside the Social Democrats. It was the only Swedish party to have two
spokespersons,
Gustav Fridolin (since 2011), who served as
Minister for Education, and
Isabella Lövin (since 2016), who served as
Minister for International Development Cooperation. This was the first time in Swedish history that the Green Party had its governmental record tested at an election. The
Centre Party (C;
Centerpartiet) was the fifth-largest party in the Riksdag with 22 seats. It was a part of the
Reinfeldt Cabinet from 2006 to 2014, and was involved in the Alliance. The Centre Party had been led by
Annie Lööf since 2011. It was subject to public attempts by Löfven to become a cooperation party, but the party traditionally leans towards the Moderate policy positions and stayed within the Alliance after the 2014 election. The
Left Party (V;
Vänsterpartiet) was the sixth-largest party in the Riksdag with 21 seats. Its leader was
Jonas Sjöstedt. He had said that the party sought to participate in a future
Red-Green coalition government. The Left Party did not support the Löfven Cabinet because it was not asked to participate in that cabinet following the 2014 general election, but supported its budget that was voted down on 3 December 2014. Following the budgetary agreement, the Left Party was what tips the left-of-centre minority into a larger minority than the Alliance. The
Liberals (L;
Liberalerna) was the seventh-largest party in the Riksdag with 19 seats. It was a part of the Reinfeldt Cabinet from 2006 to 2014, and was involved in the Alliance. The Liberals had been led by
Jan Björklund since 2007; his leadership was being increasingly criticized within the party. Opinion polls in the year after the 2014 election suggested that the party was falling significantly behind and struggling to recapture its previous level of support. Having been in charge of the school system and
integration of migrants, it came under a lot of criticism owing to falling school results and increased segregation in immigrant-dominated suburbs. The
Christian Democrats (KD;
Kristdemokraterna) had been led by
Ebba Busch Thor since 2015. It was involved in the Alliance. Despite polling below the 4% electoral threshold for most of the time between the elections, the party saw a boost in support in the time period immediately prior to the election, guaranteeing its presence in the Riksdag (which was seen as essential in order for the Alliance to be able to form a government.). The party held on by a few tens of thousands of votes last time.
Minor parties Parties with less than 4% of the vote do not get any seats in the Riksdag.
Feminist Initiative (FI;
Feministiskt Initiativ), led by former Left Party leader
Gudrun Schyman, was the country's ninth-largest party, and was represented in the
European Parliament following
the 2014 European election. The party received 0.4% of the vote in the election, compared to 3% in the previous election 2014. The
Pirate Party (PP;
Piratpartiet)
won representation in the 2009–14 European Parliament, but its subsequent runs for office had been less successful. It has been mentioned in some polls as the tenth-largest party, but appeared to be far from having a chance to break the threshold at a domestic level. The
Alternative for Sweden (
Alternativ för Sverige) was a party with no representation in the Riksdag. It was formed from members expelled from the Sweden Democrats in 2015, and was led by
Gustav Kasselstrand. The party received 0.3% of the vote, and thus failed to enter the
Riksdag in this election. ==Electoral system==
