Sweden's Left Party will vote against Magdalena Andersson as prime minister if she pursues a government with the Centre Party and the Greens that excludes the Left, deputy leader Ida Gabrielsson has said. She rejected the proposed arrangement on Sunday, warning that it would give the Centre Party leverage over a Social Democrat-led government.

Andersson, leader of the Social Democrats, announced on Sunday that she aims for a three-party cabinet made up of her own party, the Greens and the Centre Party, working closely with the Left from outside government. The Left has long demanded ministerial seats, and Gabrielsson said a party congress decision prevents it from dropping that condition. The four parties together hold 176 of the Riksdag's 349 seats.

Deadlock drags on after two failed votes

Parliament has already rejected two prime ministerial nominees since the general election on 13 September. Andersson herself was voted down on 15 October, and Centre leader Elisabeth Thand Ringqvist was rejected on 3 November by 324 votes to 25. Caretaker Prime Minister Ulf Kristersson has been given until 10 November to explore whether a government led by his Moderate Party could win enough support.

Social Democrat Anders Ygeman said talks would continue and warned it would be a failure for all four parties if they could not turn their narrow majority into political influence. Thand Ringqvist has said the Centre Party will wait to respond until the Social Democrats and the Moderates have presented their respective plans for how Sweden should be governed. No three-party government has been agreed, and political scientist Jonas Hinnfors of the University of Gothenburg warned that every side faces risks if the talks collapse.
