Somerfield has become the latest supermarket to strike a deal to ensure farmers receive an extra 2p for milk supplied on behalf of the supermarket.

A Somerfield spokesman said: “Unlike other supermarkets this increase is not short-term and it is tied into a long-term written agreement - this is an ongoing commitment to farmers and is back dated to the beginning of November.”

Somerfield has agreed with its cheese supplier, Glanbia, to pay an extra £200 per metric tonne for all cheese produced from November 1.

The Bristol-based supermarket chain sells over 10,000 tonnes of British cheddar every year and more than 600 million pints of UK milk.
