LONDON: Britain will impose a tax on excessive sugar levels in soft drinks, starting in two years’ time, to cut down on spiralling childhood obesity levels, Finance Minister George Osborne said Wednesday. “I can announce that we will introduce a new sugar levy on the soft drinks industry,” Osborne said, adding that the tax would be on drinks with more than five grammes of sugar per 100 millilitres. Britain has some of the worst obesity rates in Europe. Official data from last year showed 61.9 per cent of British adults and 28 per cent of children aged between two and 15 are overweight or obese.
