Green Party federal chairwoman Ricarda Lang in Magdeburg. Around 200 farmers honked their horns and lit fires on the sidelines of an internal Green party event.

This is not the first confrontation of this kind for party leader Lang. Lang was whistled at, insulted and prevented from leaving an event in Schorndorf near Stuttgart in mid-February. There have also been violent protests by farmers in France in recent weeks, including highway blockades that lasted for days.
