Boris vows to fight closure of Tube station ticket offices

The Tory mayoral candidate warned that passengers would be put off using the Underground if stations were unmanned and added that since Transport for London had no intention of making job cuts, its plans for the closures were unnecessary.

On the campaign trail in Harrow Mr Johnson pledged to halt TfL's proposals to close around 40 offices and said: "They do provide a great deal of reassurance to people late at night if something untoward happens, if they're scared, or if there is an affray.

"It's good to at least have a human being there to give a sense of security. That's why I think we should fight to reverse this programme of closures."

He said transport was "needlessly scary" and that he was concerned about disorder and violence on the network.

Earlier the Tory candidate claimed that Mayor Ken Livingstone had ignored the growing problem of drug-taking on buses.

Metropolitan police figures show crimes involving drug use went up by 66 per cent between April and November last year compared with the same period the year before.

He said: "It is a disgrace that Londoners have to suffer this kind of behaviour on our buses. People should be able to travel in safety with their children. When I am Mayor my extra officers will crack down on drug-taking on our buses."

But TfL said Mr Johnson had failed to take into account that overall crime on London's buses actually fell 11 per cent in that period.

The statistics showed that robbery was down 28.3 per cent, criminal damage down 22.2 per cent and theft down nine per cent.

A TfL spokesman said: "Over the six-month period referred to, 381 drugs offences were recorded out of nearly a billion passenger journeys on 8,000 buses that serve 700 different routes.

"The rate of bus related crime is now at its lowest for four years with just 15 crimes for every million passenger journeys."
