In this election, the Social Democrats would have its worst election result since 1981. However they were still extremely strong in the Municipality, and won 13 seats with 50.8% of the vote. Therefore Jesper Würtzen looked set to continue as mayor. This would eventually be confirmed.[2][3]
Electoral system
For elections to Danish municipalities, a number varying from 9 to 31 are chosen to be elected to the municipal council. The seats are then allocated using the D'Hondt method and a closed list proportional representation.
Ballerup Municipality had 19 seats in 2021
Unlike in Danish General Elections, in elections to municipal councils, electoral alliances are allowed.
