Kristersson resigns as Sweden’s centre-left takes 176 seats to 173

Swedish Prime Minister Ulf Kristersson submitted his resignation to parliamentary speaker Andreas Norlén on 17 September, hours after the election authority finished counting Sunday’s vote. The four parties around Social Democrat leader Magdalena Andersson took 176 of 349 seats. Kristersson’s right-hand bloc, including the Sweden Democrats, took 173. The gap between the blocs was 50,359 votes.

Andersson, who was prime minister from 2021 until the 2022 defeat, said voters had chosen “a new direction” and “unity” over division. She named climate policy, schools, healthcare, elderly care and immigration as the files she intends to open first. She has invited the Left, Centre and Green parties to talks. The earliest a new prime minister can take the oath is 29 September.

Why the arithmetic is tighter than the headline

One hundred and seventy-six is a majority of one over half the chamber. It is not a coalition. The Centre Party has said it will not sit in a government that includes the Left Party. The Greens are a possible partner. Even a Social Democrat-Centre pact would still need a third vote to govern. If parliament rejects four prime ministerial candidates, the constitution requires a new election.

That is why Kristersson’s letter matters. He asked to be relieved at once so the speaker could start the sounding rounds. Norlén now calls in each party and tests who can survive a vote in the Riksdag. Andersson is the only candidate with a path that does not run through the Sweden Democrats. That path still has to be built.

The Social Democrats were the largest single party, with about 28 percent. The Sweden Democrats, who had grown at every election since they entered parliament in 2010, lost vote share for the first time. Kristersson had signalled before polling day that he was prepared to give them ministerial jobs. That offer is now void. The party that was supposed to pull the right across the line instead helped drop it three seats short.

What four years of Tidö politics leaves behind

Kristersson’s government, the Moderates with the Christian Democrats and the Liberals, governed with Sweden Democrat support under the Tidö agreement. The record of those four years is a harder line on immigration and crime. Andersson’s campaign treated that record as the reason to change course. She also used Kristersson’s readiness to put the Sweden Democrats at the cabinet table as a warning. The seat count says enough voters agreed to flip the chamber, and not by much.

Dagens Nyheter reported that the Social Democrats had already opened talks with the other opposition parties. Christian Democrat leader Ebba Busch, the outgoing deputy prime minister, said it remains to be seen what happens next. That is an accurate description of a 176-173 parliament in which the prospective prime minister’s allies disagree about each other.

Sweden will spend the next two weeks in the speaker’s rooms. The policy fight that follows, if Andersson is confirmed, starts with the files she named. The political fight that could yet send the country back to the polls sits in a single sentence from the Centre Party: no coalition with the Left. Until that sentence moves, 176 seats are a majority on paper and a negotiation in practice.
