City puts health first
The move is believed to be the country's most ambitious plan for healthy eating in schools and adds an estimated pound;4 million to the authority's food bills next year.
It comes in response to health fears in the deprived city of 250,000 people. Levels of type 2 diabetes associated with poor diet were the highest in Britain, data analysts Experian said last year.

The decision needed special dispensation from the Department for Education and Skills, because schools have a legal duty to charge for meals.

The "Eat Well, Do Well" scheme has been extended this month to provide free fruit to all primary pupils.
