London's new Mayor, Boris Johnson, has unveiled Plans to ban the drinking of alcohol on London's transport system.

The ban is part of Mr Johnson's wider strategy to tackle anti-social behaviour and will come into force on 1 June. From that date, anyone caught drinking on the city's Tube, buses, trams or the Docklands Light Railway could be asked to stop or even be thrown off if they refuse.

The ban on the London Overground will take longer, as Transport for London has to apply to the Department for Transport for permission to enforce the bar on the consumption of alcohol.

Don Shenker, chief executive of Alcohol Concern, said: "Public drinking and the behaviour sometimes associated with it can, and does, deeply affect people's ability to enjoy public spaces.

"Taking a firm approach to public drinking in this way sends a strong message that public drunkenness is socially unacceptable."

But the Rail Maritime and Transport (RMT) Union's leader Bob Crow said: "We are in favour of any measure that will make our members' lives safer and curb anti-social behaviour, but it appears that this really hasn't been thought through very well and could well make matters worse.

"We are being told that it will be our members who will have to approach people drinking and ask them to stop - but the mayor hasn't asked us what we think.

"Perhaps the mayor will come out with his underpants on over his trousers like Superman one Saturday to show us how it should be done, and maybe tell a crowd of Liverpool supporters that they can't drink on the train."
