Supermarkets that apply for 24-hour licences to sell alcohol could encourage “problem drinking”, Alcohol Concern has said.

Tesco, Asda and Sainsbury have all applied for licences to sell alcohol round the clock under new drinking laws which will come into force in November.

However, the charity said that it was concerned that increased retail hours could result in a rise in drinking and problem drinking.

It has urged supermarkets to ensure that they do not offer cheap drink promotions or serve customers who are underage or drunk.
