The Swedish prime minister, Stefan Löfven, is stepping down after lost a mandatory vote in confidence.
It is unclear who will form the next government neither major political bloc holds a majority.
In an election on 9 September, there was a hung parliament. Löfven’s centre-left party won 144 seats, which is just one more than the centre-right opposition Alliance.
Analysts are expecting Ulf Kristersson, the leader of the Alliance party, to try to form a new government. He will need support from the anti-immigration Sweden Democrats or the centre-left.
Jimmie Åkesson, leader of the Sweden Democrats, said: “If Ulf Kristersson wants to be prime minister it can only happen with my help.”
The Alliance of the Moderates, Centre, Liberal and Christian Democrats have all said they do not plan to negotiate with the anti-immigration party.
Mattias Karlsson, the Sweden Democrats’ parliamentary group leader and chief ideologue, previously wrote on Facebook: “Our enemies have really forced us into a life-and-death struggle for our culture and our nation’s survival. There are only two choices: victory or death.”
The Swedish Democrats manifesto states: “We want to stop receiving asylum seekers in Sweden and instead go for real aid for refugees. We want to enable more immigrants to return to their native countries.”
Sweden will hold another election within three months.
