Jamie Oliver says he has 'given up on politics'

TV chef Jamie Oliver says he has given up on trying to change governments' attitudes to healthy eating, as he visits New York in a bid to tackle obesity there.

He is equipped with a "Food Revolution" truck, which is an interactive mobile kitchen, designed to teach children about healthy eating.

However, he told the BBC's Charlie Stayt that the UK is still the unhealthiest country in Europe, and criticised the education secretary for "removing nutritional standards".
