**Sweden's September 13, 2026, parliamentary election produced a narrow centre-left victory and confirmed seats for all eight established parties in the 349-seat Riksdag.** Preliminary counts showed the Social Democrats-led opposition bloc (Social Democrats, Left Party, Centre Party, Greens) ahead by one seat at 175–174 over the incumbent right-wing grouping (Moderates, Christian Democrats, Liberals backed by the Sweden Democrats). All parties cleared the 4% national threshold, with the Liberals reaching roughly 5.3–5.4% after polling near or below it in earlier surveys. The Social Democrats remained the largest party at about 28%, while the Sweden Democrats fell to around 17.5% (down from 2022). The campaign centred on crime, immigration, the economy, and security, with late tightening of the blocs driven by shifts among undecided voters and stronger-than-expected Liberal performance. Final seat allocation awaits completion of late and overseas ballot counting, expected shortly.
