How to watch Sweden’s election like a pro

Swedish voters will head to the polls on Sunday to decide the composition of the 349‑seat Riksdag, a contest that could either cement a left‑wing government led by former prime minister Magdalena Andersson and the Social Democrats or usher in a historic right‑wing administration headed by incumbent prime minister Ulf Kristersson, whose coalition would include the far‑right Sweden Democrats (SD) in ministerial posts for the first time. The election is especially pivotal because Sweden joined NATO only a year ago, and the outcome will shape the nation’s security posture toward Russia and its broader role in European defence. Early voting, which opened on Aug. 26, has set a record for participation, and the final two weeks of campaigning have seen polls tighten from a comfortable left‑wing lead to a near‑dead heat, according to SVT forecaster Gustav Karreskog Rehbinder.

The decisive factor may lie in Sweden’s proportional representation system, which allocates seats according to each party’s share of the national vote but excludes parties that fail to reach a 4 % threshold, giving smaller parties the potential to tip the balance of power. In the 2022 election, eight parties entered parliament, and the current right‑wing bloc relies heavily on the SD’s 20 % vote share, despite the party’s controversial origins in the 1980s neo‑Nazi movement. Kristersson has pledged to grant the SD ministerial portfolios, including possibly defence or foreign affairs, a move that Andersson has warned would “not be good for Sweden.” The Sweden Democrats, led by Jimmie Åkesson, argue that taking government responsibility is a natural next step, eyeing a prime‑ministerial bid in 2030.

Both blocs agree on maintaining Sweden’s support for Ukraine, reflecting the country’s historic wariness of Russian aggression, while campaigning on domestic issues such as tax relief, housing, health and dental care. Regional and local elections will be decided simultaneously, and with more than 8 million registered voters and historically high turnout—over 80 %—the results will not only determine the next government but also signal how Sweden, as NATO’s newest member, will navigate security challenges and the broader European debate over integrating far‑right parties into mainstream politics.
