Tractors leave Brussels during a demonstration in Brussels November 27, 2012. Thousands of dairy farmers from all over Europe took part in the protest called " 1000 tractors to Brussels' to urge politicians to take efficient legislative measures for the milk market and to listen to farmers' demands for cost-covering prices and fair remuneration, according to the organisers.
