Milk producers from across Europe will descend on Strasbourg today, to protest against falling prices.An estimated 3000 will march with tractors and cows from the centre of the city to the European Parliament building – where the first session of the new assembly is taking place. The campaigners say their livelihoods are in jeopardy: “The aim is to agree on a good price so that we can produce our milk and have a decent salary in return,” said Emmanuel Tassignon, a union leader. Blockades in Belgium yesterday coincided with a meeting of EU agriculture ministers in Brussels. Ministers agreed to extend some limited support for the milk industry until next year. However, the European Commission has refused to go back on a decision to scrap milk quotas.
