Thomas Diener plans to switch from the CDU to the AfD. In protest, representatives of the CDU, SPD, Linke and Grüne left the district council meeting.
Thomas Diener's switch is viewed as crossing the firewall against the AfD. The other factions responded by leaving the meeting.
Important resolutions could therefore not be passed. The session ended without the planned decisions.
The parties involved expressed their displeasure over the party switch. They emphasized their stance on cooperation with the AfD.
