Taxis caused gridlock in London yesterday during a protest at the Transport for London headquarters.
The demonstration had been organised over claims that the capital's taxi trade is being 'destroyed' by the local governing body.
Drivers caused travel chaos by parking their black cabs outside Palestra House, which is opposite Southwark Tube station.
Video has emerged from the scene showing taxis blocking every surrounding road as police officers try to keep traffic moving.
The Independent Taxi Alliance said in a statement about the protest: "It's perfectly clear to us all, TfL have an agenda to destroy the London taxi trade.
"The message behind the protest is simple: No more deregulation and no more dismantling of the taxi trade."
Peter Blake, TfL's director of service operations, said before the demonstration took place: "There is no need for this protest that will cause unnecessary disruption to people trying to go about their business.
"The Mayor has recently launched a comprehensive Taxi and Private Hire Action Plan that is aimed at driving up standards and improving safety.
