Sweden's centre-left opposition secures narrow one-seat lead with 175 projected Riksdag seats

Narrow parliamentary projection

Sweden's centre-left opposition led by Social Democratic leader Magdalena Andersson is on track to win a one-seat majority following Sunday's parliamentary election. Projections published on Wednesday by public broadcaster SVT assign 175 seats in the 349-seat Riksdag to the four-party opposition bloc, compared to 174 seats for Prime Minister Ulf Kristersson's right-wing coalition. At 99.6% of districts counted, the opposition held 49.4% of ballots against 49.0% for the governing bloc, with the margin shifting between one and three seats during the day. At 18:47 local time on Wednesday, 29,169 votes separated the two political groupings. SVT calculated the probability of an opposition victory at 99.9%.

The probability of a turnaround at this stage is so low that we can say with certainty that the opposition will win the most seats in this election.

Counting the late ballots

Sweden's Election Authority continued tallying late-arriving advance and overseas ballots, known as Wednesday votes, across 6,607 of the country's 6,626 total districts. The national electoral map comprises 6,312 regular districts alongside 314 specialized collection districts (uppsamlingsdistrikt) designated for late returns. Officials in Gothenburg, Sweden's second-largest city, announced that local counting would continue through Thursday. The authority estimated total late ballots at roughly 300,000, exceeding the 227,000 late ballots tallied in 2022. While late ballots in Swedish electoral history rarely overturn election night standings, overseas votes swung the 1979 election against Olof Palme when 8,500 votes separated the blocs.

We expect a larger number of votes this year than in previous elections. We cannot know the number in advance, but we estimate that there are around 300,000. This means that the count will probably take a long time in many municipalities and that we will not have an updated preliminary result until Thursday.

Party shares and campaign platforms

The Social Democrats remained the largest party in parliament with 28% of the vote, representing a decline of 2.3 percentage points. The Sweden Democrats, who campaigned on a joint platform with the governing Moderates, Christian Democrats, and Liberals, recorded their first election vote share drop since 1988. The governing coalition campaigned on reductions in asylum seekers to 40-year lows and stricter measures against gang crime. The centre-left opposition focused its campaign on the domestic economy, inflation, and public funding for the welfare state. Neither side is expected to alter Sweden's pro-Western foreign policy or support for Ukraine.

Coalition negotiations and conflicting red lines

Andersson faces difficult negotiations to secure a viable governing majority among three distinct partner parties: the Centre Party, the Left Party, and the Green Party. The Centre Party, which previously served in centre-right governments from 2006 to 2014, has ruled out sitting in cabinet alongside the Left Party. The Left Party has demanded cabinet representation following its electoral performance, while the Greens propose halting the restart of nuclear power and easing immigration rules. Business groups have expressed concerns regarding tax proposals from the Left and Greens. Kristersson has not conceded defeat, and a parliamentary investiture vote to confirm a prime minister will take place on 29 September at the earliest.
