Mayor after election

Sisse Marie Welling
Green Left

The 2025 Copenhagen Municipal election was held on November 18, 2025, to elect the 55 members to sit in the regional council for the Copenhagen Municipal council, in the period of 2026 to 2029.[1] Sisse Marie Welling from the Green Left, would win the mayoral position. [2]

Background

In the 2021 election, Sophie Hæstorp Andersen from the Social Democrats became mayor for her first term, despite the Social Democrats failing to become the largest party for the first time in more than a hundred years.[3] Instead, the Red–Green Alliance won the most seats, but failed to win the Lord mayor position.[4]

Lord mayor Hæstorp Andersen, stepped down from the position which was revealed on August 29, 2024,[5] and instead became Minister of Social Affairs. Pernille Rosenkrantz-Theil was later revealed to become the leading candidate from the Social Democrats for this election.[6]

Electoral system

For elections to Danish municipalities, a number varying from 9 to 31 are chosen to be elected to the municipal council. However Copenhagen Municipality has, as the only municipality, a city council instead of a municipal council. In the city council 55 seats are contested.

The seats are then allocated using the D'Hondt method and a closed list proportional representation.

Unlike in Danish General Elections, in elections to city councils, electoral alliances are allowed.
