A group of medical professionals has written to the Sunday Times to call for a minimum price on alcohol to be set at 50p per unit.
The group, headed by Professor Sir Ian Gilmore of the Alcohol Health Alliance and British Society of Gastroenterology.
The letter said: "Young people and families all too often suffer the consequences of problem drinking, with some 2.5m children in the UK living with a hazardous drinker.
The group said a minimum unit price would target the heaviest drinkers, and that while it was not a silver bullet, it would make "a real difference".
Other signatories to the letter included: Dr Vivienne Nathanson, British Medical Association; Dr Clare Gerada, Royal College of General Practitioners; and Dr Hilary Emery, National Children's Bureau.
