A 24-hour strike on London’s Underground has disrupted the travel plans of millions of commuters.
The walkout by members of two unions is in protest over plans to axe 800 ticket office jobs.
It is the second day of action of its kind with two more planned for November if the dispute remains unresolved.
Transport for London say they laid on 100 extra buses in an attempt to counter the industrial action.
The Mayor of London Boris Johnson has called for changes in the law to make it more difficult for unions to call their members out.
Johnson called the strike “nakedly and blatantly political.”
Current legislation allows unions to call for a strike if they secure a majority vote in a ballot, no matter what percentage of their members take part.
