Labour peer Lord Robert Winston has warned the Government that extending licensing laws could result in higher levels of alcohol abuse. He said there should have been trials first to gauge its possible effects and said alcohol was the "biggest medical problem we face - probably bigger than smoking". Professor Roger Williams, one of the country's leading liver disease consultants, backed him. Williams who carried out the first liver transplant in 1968 described the decision to allow pubs to stay open later as "hideous". He said it would inevitably lead to more alcohol-related deaths.
