Jamie Oliver set to dig deep to feed primary school children

At last some good news for David Cameron . He has a poster boy for his Big Society . Jamie Oliver has announced that he's going to be investing millions of his own fortune in a scheme to improve school dinners in UK primary schools . Details of the working of the scheme are sketchy, but Oliver wants to create a fund of money which individual schools can bid for – those with "all their ducks in a row... [will receive] hundreds of thousands of pounds". "[The money] will build gardens, build school kitchens, give them seeds and fruit trees as well as teaching collateral," he told the BBC. Last month, a study found that Oliver's Feed Me Better campaign had boosted pupils' test results in Greenwich, London and attendance rates had increased by 15% . The researchers said the campaign was "more effective than literacy hour". Oliver said he was aiming to kick off with 20 to 40 schools a year, eventually rolling out the project to around 1,000 primary schools. Oliver has proved before that his low-slung jeans have deep pockets. First, there was the Fifteen restaurant project, which supports a charitable foundation that trains chefs from disadvantaged backgrounds, and at the weekend it was revealed that Oliver will be 22nd on the Sunday Times Giving List – he is reputed to have given away £2.7m to charity last year. Talking about the scheme, Oliver used words that should make the Tory leader's big grin return. "We'll use that private, entrepreneurial, idea – that is obsessed by relevance and making a true, real tangible change to children and their parents – to then come up with a model. And we'll say to government, 'now I've proved it – let's do it'."
