Supermarkets are now selling beer cheaper than the mineral water because of the shop price wars.
The research by Channel 4's Dispatches programme found that Asda's lowest-priced beer is 72p a pint with Perrier going for 76p a pint and at Sainsbury's, Foster's lager is 72p, while, 15 cans of Strongbow sets you back just 8 pounds, making it 69p a pint, which is 7p less than Perrier, the Daily Star reported.
Tesco now offers its cheapest lager at 69p a pint compared with 73p for the same volume of Perrier water.
Katherine Brown, director of Institute of Alcohol Studies said that the government has completely broken its commitment to tackle pocket-money priced alcohol, which was increasing rates of disease and disorder in UK.
However, the British Retail Consortium, who is representing supermarkets, said that the retailers' were working efficiently with the government to provide clear health information and they were committed to building on these.
