Columns of tractors rolled into Berlin on Monday as farmers gathered for the climax of a week of demonstrations against a plan to scrap tax breaks on the diesel they use, a protest that has tapped into wider discontent with Germany’s government.

Police said late Sunday evening that the space set aside for vehicles in front of the Brandenburg Gate, where Monday’s demonstration was being held, was already full. Over the past week, farmers have blocked highway entrances and slowed down traffic across Germany with their protests, intent on pushing Chancellor Olaf Scholz’s government to abandon the planned cuts entirely.
