A pub manager's union is calling for the Government to make it illegal for pubs to serve most drinks with an abv above 5% after 11pm.
The National Association of Licensed House Managers (NALHM) also vowed to back any manager who is being asked to run what they consider to be an irresponsible drinks deal after 11pm.
The Transport & General Workers Union (T&G), of which NALHM is part, is to lobby MPs to force an amendment to the Licensing Act that will outlaw the serving of drinks with a high alcohol content after 11pm.
Brian Revell, who represents NALHM at the T&G, is to meet members of the All Party Parliamentary Beer Group to persuade them to support the proposal.
The details of the plan are yet to be decided, but members are considering making an exemption for wine.
The decision was taken at a NALHM meeting last week, which was called to discuss trading under the new licensing regime.
NALHM wants to follow the lead of Finnish capital Helsinki, where it is illegal to serve drinks with a high alcohol content late at night.
The move would mainly be for the benefit of pubs away from the high street that do not currently open late.
'We were trying to come up with some ideas for the guys in the suburbs,' said NALHM president Dave Daly. 'Some of them
are a bit scared about operating after 11pm.'
NALHM members agreed that banning high-alcohol drinks after 11pm would mean people would still stay late in the pub but would not get drunk and cause problems.
The union also urged managers to carry out a risk assessment of drinks promotions they are asked to operate - and refuse to do them if they think it could fuel disorder.
Daly said NALHM members were concerned that councils and police were targeting 'problem' pubs and clubs as the new laws are being implemented. He pointed to the closure of high-profile clubs such as Syndicate in Blackpool and Hippodrome in London's Leicester Square.
