What did your lunch consist of today? For those still on New Year diets, something low-cal and wholesome. For others, perhaps a sandwich bought at the nearby supermarket.

 For one Westminster schoolchild, lunch consisted of two custard crème biscuits sent from home. For another, it was a pre-wrapped croissant. When a teacher asked why the child was eating it so slowly, he replied: ‘I was told not to ask for school lunch because we can’t afford it.’
