Greater controls over what is eaten at school breakfast clubs are being urged after the discovery of fried sausages, crisps, sausage rolls, biscuits, hot chocolate, squash and doughnuts on some menus.

In one school there was no vitamin C, and the salt intake was double that of other schools investigated. None of the breakfast clubs surveyed provided fruit or fruit juice.

Researchers from the University of East Anglia also found that children who attended the clubs - launched by the Government four years ago to promote healthy eating and school attendance - were eating significantly more fat and salt.
