The Association of Chief Police Officers (Acpo) wants the government to modernise the current legislation, which dates back to 1964.

The Chairman of Acpo's Liquor Licensing Sub-Committee Allan Charlesworth, said changes were needed to tackle alcohol-related anti-social behaviour.

Speaking at a conference in York, Mr Charlesworth said trouble arising from drinkers leaving pubs and clubs at the same time could be avoided by allowing different closing times.

Mr Charlesworth, who is Assistant Chief Constable of West Yorkshire, also called for improved enforcement of laws by police.

Tougher policing, he said, would prevent drug pushing and under-age drinking.

The needs of publicans, customers and neighbours would be better served by licensing becoming the responsibility of local authorities, as in Scotland, he added.

Home Office Minister George Howarth told the conference the government was already reviewing licensing laws, including the extension of opening hours.

Mr Howarth said there was likely to be a temporary relaxation for Millennium celebrations.
