Sweden's September 13 parliamentary election delivered a narrow centre-left majority of 176 seats against 173 for the incumbent right-wing bloc, prompting Prime Minister Ulf Kristersson's resignation and positioning Social Democrats leader Magdalena Andersson as the primary candidate to form the next government. Polling trends throughout the campaign, combined with the Social Democrats remaining the largest single party, underpin trader consensus around Andersson despite the bloc's slim edge. Government-formation talks have since stalled after the Left Party backed a Moderate speaker and refused full coalition alignment, returning the exploratory mandate without resolution as of late September. This leaves Andersson favored in the Riksdag's sequential Speaker-led process but highlights ongoing coalition hurdles with the Centre Party and internal left divisions that could still shift support toward Kristersson or another figure if negotiations extend.
