Young people aged under-21 years old could be banned from buying alcohol from the off-trade, as part of voluntary scheme to be trialled by the London Mayor in Croydon. The pilot initiative will be tested by supermarkets and off-licences in the South London borough on a voluntary basis. Boris Johnson endorsed the project yesterday during Mayor’s question time, calling it a “very interesting solution to the huge problem of binge drinking”. Johnson said: “Where we have got particular problems in particular areas, off-licences and supermarkets should stop the sale of alcohol to the under-21s. That is the kind of solution that I think Londoners are looking to us to provide. I do think this is something where the boroughs can take a lead and banish the scourge of binge drinking.” Industry body, the Association of Licensed Multiple Retailers (ALMR) responded to the initiative with interest. Nick Bish, chief executive of ALMR, said: “We warmly welcome Cllr O’Connell’s comments about cheap alcohol in off-trade outlets being linked to anti-social behaviour. “As we at ALMR have long known, low-cost sales for unsupervised drinking is fuelling binge drinking in the young. We look with interest at any initiative that addresses these irresponsible buying and selling practices. “However we are cautious of the potential for this voluntary scheme to become legislation in what is an already over-legislated industry, and would take this opportunity to remind the bureaucrats that pubs and bars are in fact twice licensed already.”
