Jamie Oliver criticises parents who feed their children junk food in his new television show, Jamie's Return to School Dinners.

In the programme, to be broadcast on Channel 4 on 18 September, the celebrity chef rails against mums and dads who send their kids to school with packed lunches full of fatty and sugary treats.

He rages: “I've spent two years being PC about parents. Now is the time to say: 'if you're giving your young children fizzy drinks you're an arsehole, you're a tosser. If you give them bags of crisps you're an idiot'.”
