Since all-day drinking was introduced, at least 3,000 premises have been given 24-hour licences, including 24 in Tower Hamlets and 12 in Newham. Alcohol Concern said alcohol-misuse was costing casualty departments up to £500million a year, with 70 per cent of admissions after midnight due to drink. "Too often, emergency services are left to pick up the tab," it added.
