Mayor before election Thomas Gyldal Petersen Social Democrats Mayor after election Thomas Gyldal Petersen Social Democrats

In the last election, they won 12 of the 19 seats, and Thomas Gyldal Petersen would therefore go into his third full term as mayor.^[a][1]

In this election, however, they would lose their absolute majority. Only one party from the blue bloc would win representation though, and 14 of the 19 seats would be for parties of the traditional red bloc. There would be majority with all the elected red bloc parties, that would support Thomas Gyldal Petersen as mayor.^[2][3]

This election would be one of only four, where Venstre failed to win representation.
