The next Swedish general election on 13 September 2026 will determine the 349-seat Riksdag and subsequent government formation through post-election negotiations. Current polls show the centre-left bloc—led by the Social Democrats and potentially including the Left and Greens—holding a clear lead near or above 55%, compared with roughly 42-46% for the incumbent right-wing Tidö parties (Moderates, Christian Democrats, Liberals, supported by Sweden Democrats). The proportional electoral system and 4% threshold favor bloc majorities around the 175-seat mark, with recent campaigning centering on crime, security, immigration, and the economy. Coalition talks after election night typically involve cross-party support arrangements or formal agreements, and any shift in final turnout or late polling could alter viable governing combinations.
