Farmers' protests: Political Ash Wednesday for the Greens. Dozens of tractors on the access roads to the town hall, where the Greens want to meet.

A large pile of dung was dumped in front of the hall. The Greens have been meeting in Biberach for years, where a lot of federal celebrities are expected again this year. In addition to Agriculture Minister Cem Özdemir, who is considered a promising candidate to succeed Prime Minister Winfried Kretschmann, Federal Chairwoman Ricarda Lang will take the lectern.
