Palace says cheesemakers to Queen must keep up with environmental standards or risk removal of coat of arms
The Queen could remove the royal warrant from her favourite cheddar cheese after its producer filled a river with a noxious black sludge, the Guardian has learned.
Sources at Buckingham Palace said the warrant for Davidstow cheddar, produced by Dairy Crest, could be removed on environmental grounds after it was fined £1.5m by the Environment Agency.
