2021 Ærø municipal election

The first election following the 2007 municipal reform, led to the Conservatives winning the mayor's position.

[1] In the previous election, Ole Wej Petersen from the Social Democrats had won the mayor's position, after Jørgen Otto Jørgensen didn't stand for re-election.

Venstre would only win 9.5% of the vote, the second lowest of any municipality in the Funen constituency.

In the end Peter Hansted would become the mayor, as a broad agreement between the Social Democrats, the Conservatives, the Green Left, Venstre and Ærø Plus was agreed on.

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