In 2020 he faced a challenge, as the government planned a pre-removal detention center to be built in Langeland. People of Langeland began protesting, and his party's position on the political spectrum suggested that he should be open to the idea. Eventually, he ended up coming out against the plans of the government.[2] He would eventually succeed with his opposition on the topic.[3]
He was expected to be re-elected for this election.[4][5]
In the election result, the Green Left would enjoy a small increase in their vote share. The traditional red bloc would win 9 of the 15 seats, and Tonni Hansen looked destined to continue for a second term. It was eventually confirmed that he had secured a second term.[6][7]
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.
Langeland Municipality had 15 seats in 2021
Unlike in Danish General Elections, in elections to municipal councils, electoral alliances are allowed.
