The September 13, 2026, regional election produced a narrow rödgrön majority of 51 seats for Social Democrats, Centre Party, Greens, and Left Party in the 101-seat regional council, ending the prior Moderate-led arrangement. Mattias Ottosson, the Social Democrats’ top regional candidate and former Riksdag member with local roots, is positioned to lead the incoming executive board under standard Swedish practice of awarding the chair to the largest party in the governing coalition. Ongoing negotiations among the four parties continue to shape the final agreement, yet trader pricing reflects the confirmed electoral shift and Ottosson’s established frontrunner status. Incumbent Marie Morell and other listed candidates face sharply reduced prospects absent an unexpected reversal in coalition formation.
