The SD was founded by Nazi sympathisers and had been shunned by the mainstream for decades. But a focus during the election campaign on issues around immigration and violent crime have put the SD’s agenda at the heart of mainstream Swedish politics like never before. Founded in 1988, the SD struggled for two decades to win enough votes to elect any MPs at all. But since entering parliament in 2010, the party has increased its share of the vote in three successive elections and is now the second-largest party.
