School pupils in Scotland have called for bargain booze to be banned from supermarkets.

Teenagers from the All Saints Secondary School in Glasgow submitted a petition to the Scottish parliament last week calling for an end to cheap alcohol promotions and action on binge drinking.

The pupils said they had carried out their own price comparisons and found beer and lager for sale in multipacks for as little as 20p per can in their local store - less than a can of soft drink.

Pressure is mounting in Scotland for action on cheap booze. At its annual conference last month the Scottish National Party pledged that, if elected, it would ban deep discounting drinks promotions in grocery stores.

Fiona Moriarty, director of the Scottish Retail Consortium, said: "We believe price is only one of several issues that should be tackled."
