Liberal Democrat licensing spokesman Don Foster has thrown his weight behind the campaign against cheap supermarket alcohol, calling the deals "totally irresponsible".
Foster has put his name to the Early Day Motion, currently signed by 84 MPs, that urges supermarkets to stop using alcohol as a loss leader because it encourages binge drinking.
The Bath MP told the MA: "Binge drinking is a huge problem. The figures for alcohol-related violent incidents and admissions to A&E departments at our hospitals are at record levels. While there are numerous ways in which the problem should be tackled, it's clear that ultra-cheap prices don't help.
"With a pint of orange juice more expensive than a pint of beer it's hardly surprising. Many pubs have dropped their 'happy hours' and other cheap drink offers. But many supermarkets and off-licences are doing the opposite.
"Of course competition will mean 'competitive' prices, but using alcohol as the loss leader to get people into a particular supermarket is totally irresponsible."
