KNUTSFORD, UNITED KINGDOM – MARCH 16: Cans of lager line the shelves in an off licence on March 16, 2009 in Knutsford, England. The Government’s Chief Medical Officer Sir Liam Donaldson has demanded a minimum price to be set on some alcoholic drinks in an attempt to tackle binge-drinking and alcohol-related illnesses, suggesting a 50 pence per unit tariff which could result in every can of beer costing at least 1 GBP and a bottle of wine a minimum of 4 GBP.
