Andersson believes that there are currently no conditions for her to become prime minister.
She blames V, which announced on Sunday that it will support the Moderate Party's (M) candidate for Speaker of the Riksdag, not the Social Democrats'.
"V has chosen to cooperate and join forces with M in the speaker election. Then I will have to draw the consequences of that choice," says Andersson.
Stepping back
A little over a week ago, she was tasked by the Speaker with exploring the possibilities of forming a new government. Andersson is now handing that task back to the re-elected Speaker Andreas Norlén (M).
Andersson believes that the assignment should now go to M leader Kristersson, V leader Nooshi Dadgostar, or some other party leader in the "new constellation".
Now we have a new constellation in the Swedish Parliament and then it is reasonable that one of the party leaders gets the assignment, she says.
Pressuring V?
However, V denies that it is now "collaborating" with M and insists that Andersson is the party's only candidate for prime minister.
But V continues to demand to be allowed to sit in an S-led red-green government.
V's vote for M's candidate for speaker can be interpreted as V wanting to show that it is serious about its demand. Officially, however, V explains its decision to vote for Norlén by saying that his experience is needed in the difficult government formation process that is now underway.
Andersson's claim that V "collaborates" with M can also be interpreted as a way for S to try to pressure V by showing that the alternative will be a right-wing government unless V drops its demand for ministerial posts.
Belong together
According to Andersson, the Speaker's question and the government question belong together.
It is normal for the largest party in a government to hold the position of speaker, she says.
Andersson believes that V's support for M's speaker candidate should therefore also mean that V wants to see an M-led government.
However, the S leader has not given up on becoming Sweden's next prime minister, but simply states that "at the moment" there are no conditions for it.
She also thinks it is too early to start talking about snap elections if a new government cannot be formed. Andersson points out that the parties have always managed to avoid this after previous elections.
A special election is to be held after the Riksdag voted against the Speaker's proposed candidates in four prime ministerial ballots. No prime ministerial ballot has yet been held.
