Sweden heads to the polls Sunday in an election that could hand the far-right Sweden Democrats their first-ever seats in government, even as fresh polling shows the country's opposition bloc holding a solid — if narrowing — lead over the sitting prime minister.

A survey released this week found the four-party opposition led by Social Democrat leader Magdalena Andersson drawing 51.3% of voter support, against 46.6% for Prime Minister Ulf Kristersson's governing coalition of Moderates, Christian Democrats and Liberals. That 4.7-point gap has shrunk sharply from the 8.9-point lead the opposition held in June, according to Bloomberg's polling analysis.

The Sweden Democrats' moment

Kristersson's minority government has governed for years only with the outside backing of the Sweden Democrats (SD), a party with roots in Sweden's neo-Nazi fringe that has spent the past decade rebranding itself into the country's second-largest political force. The latest numbers put SD at 19.5% support. What's changed this cycle is the so-called "Sweden Promise": an explicit pledge from Kristersson's bloc that a re-election victory could finally bring SD actual cabinet seats for the first time, rather than the arms-length confidence-and-supply arrangement it has held since 2022.

A RE-ELECTED GOVERNMENT COULD PUT A FAR-RIGHT PARTY IN CABINET FOR THE FIRST TIME

That prospect has energized both sides of Sweden's political map. Andersson's opposition — the Social Democrats alongside the Left, Green and Centre parties — has cast the election as a last chance to block the Sweden Democrats' normalization at the highest levels of government. Kristersson's camp argues four more years of stability, and closer integration with a party that already effectively shapes its immigration and law-and-order agenda, is preferable to a fractured left-wing coalition.

Adding to the uncertainty, a separate poll reported by U.S. News shows the junior Liberal party now clearing Sweden's 4% parliamentary threshold — a shift that, if it holds Sunday, would hand Kristersson's coalition a firmer seat count than earlier polling suggested and complicate the opposition's path to power.

Sweden's 349-seat Riksdag is entirely up for election, with full results expected within hours of polls closing Sunday night local time. A hung or narrowly divided parliament — a realistic outcome given how close the two blocs have pulled together — could leave coalition talks dragging for weeks, as they have after each of Sweden's last several elections.
