Dairy farmers and milk processors are being urged by politicians to agree on a new code of practice.

Environment Secretary Caroline Spelman and Farming Minister Jim Paice will host talks later after days of protests about the price of milk, with the latest blockades last night in Bridgwater, Worcestershire and Shropshire.

Farmers are angry at a planned price cut by some supermarkets of 2-pence per litre, which they claim will put many out of business.
