Magdalena Andersson has failed in her first attempt to form a government, she told Speaker Andreas Norlén on Tuesday morning.
But she will still face a vote for prime minister on Thursday because Norlén wants to put pressure on the parties.
"The Centre Party has taken constructive initiatives to move the process forward and has been clear about the political direction we want to see for Sweden," says Centre Party leader Elisabeth Thand Ringqvist in a written comment.
She will return to the question of how the Centre Party will vote on Thursday.
The red lines between the Left Party and the Centre Party remain, even though representatives of the parties met at Högberga farm on Lidingö last Friday.
Dadgostar urges
The Left Party demands ministerial posts, while the Centre Party still cannot accept a government that includes the Left Party.
"Unfortunately, there are still parties that do not accept the parliamentary reality reflected in the election results. For the process to move forward, clear leadership that recognises the parliamentary reality is now required," says Left Party leader Nooshi Dadgostar in a written comment.
Green Party spokesperson Amanda Lind still believes in a majority government consisting of all four parties: the Social Democrats, the Left Party, the Centre Party and the Green Party.
“That's what we are working for,” writes Lind.
L: Weak display
The Tidö parties have sharply criticised Magdalena Andersson's leadership.
"A weak display of leadership from Andersson. Even though her side won the election, she lacks a plan to form a government. In Thursday's prime minister vote, the Liberals will vote against her," writes Liberal Party leader Simona Mohamsson.
"Nothing new on the Western Front," comments Christian Democrat leader Ebba Busch.
Ulf Kristersson (M), who leads a caretaker government, welcomes the Speaker's announcement.
"Since 176 members of the Riksdag (the Swedish parliament) want Magdalena Andersson to form the next government, it is natural that the Riksdag will test her leadership," he writes in a comment.
