The Campaign for Real Ale (CAMRA) has joined the call to stop supermarkets selling cheap alcohol.
A survey by CAMRA has revealed that in some supermarkets Fosters and Carlsberg was available for the equivalent of just 54p a pint - or 16p before tax.
CAMRA chief executive Mike Benner said: "The ridiculous practice of the major supermarkets selling below cost for alcohol to out-price each other is reckless, irresponsible and dangerous. To put it in perspective some bottled water in the supermarket costs 49p a pint and water is not subject to excise duty as alcohol is."
CAMRA believes that irresponsible drinks promotions in the off trade are a major cause of binge-drinking incidents yet it is licensed premises that suffer the fallout while supermarkets continue with impunity.
Mike Benner added: "Pubs often come under unjustified attack for encouraging binge-drinking, yet the industry has committed itself to curb irresponsible drinking and cheap alcohol promotions in recent years. This hard work is undermined by supermarkets selling enormous quantities of alcohol at prices that simply cannot be justified.
"Something has to be done now to make supermarkets realise the damage these promotions can cause."
CAMRA is urging consumers to lobby their MP to sign Early Day Motion 495 put forward by MP John Grogan, drafted by The Publican, calling for supermarkets to stop selling alcohol as a loss leader.
