A University of Oxford director is calling for a "fat tax" to get the British eating more healthily and cut back on fizzy drinks, chocolate, crisps and pasties.
Health promotion research group director Mike Rayner has suggested a 12p tax on cans of pop, with the Treasury manipulating people into healthy eating, as taxes have been used to curb drinking and alcohol use.
After his film was aired, he debated his ideas in the studio with MPs Angela Eagle and Steve Webb .
