Supermarket booze is so cheap, children as young as 12 can buy four times the weekly limit for men with their pocket money.
That is the startling news delegates at Alcohol Concern's Cheap at Twice the Price conference will hear today.
A report by the lobby group found that the weekly average pocket money for a 12-year-old (£9.53) meant they could buy three large bottles of Budweiser and two big bottls of WKD Vodka Blue at Co-Op. That is 17 units of alcohol.
At Sainsbury's, they could buy 10 x 207ml bottles of Budweiser for £6.59.
The Competition Commission cleared the supermarkets of any wrong doing in using alcohol as a loss leader last week.
During last year's football World Cup, the big four supermarkets sold £112.7m worth of alcohol below cost.
"Cheap alcohol promotions help explain just why those young people who drink can afford to do so at far greater levels than in the past," Don Shenker of Alcohol Concern told the Daily Telegraph.
Alcohol Concern is part of the newly formed Alcohol Health Alliance, along with 10 other lobby groups, which is seeking an tax hike on alcohol across the board.
The Government's own independent review into pricing, promotion and harm is due to report back in April next year.
