More than 200 taxi drivers have brought central London to a halt in a protest at the Olympic Games lanes.
Blaring their horns, the cabbies took their case to Parliament Square, creating gridlock in the heart of the capital with the jam swiftly spreading to Millbank and Whitehall.
London’s iconic black cabs are being excluded from the 30 miles of games lanes, which have been reserved for Olympic competitors, officials and sponsors.
Dubbed “Zil lanes” by critics, they come into force on Wednesday next week. Drivers who transgress face a £130 fine.
The restrictions will ban drivers from the lanes, making journey times across the capital longer and dearer for passengers.
Many cab drivers have said they will leave London during the Games rather than put up with the frustration of navigating the capital’s traffic.
"There will be no access to these lanes for any traffic apart from the Olympics family.
"Taxis are excluded, which is unacceptable and wrong. This is a working city and we need to get around and do our job," said Jonathan Myers, of the United Cabbies group union.
“We've come to Parliament so MPs can wake up and hear what we're talking about."
Bob Crow, general secretary of the RMT union, which has a number of cab drivers in its membership, said:
“It’s a scandal that a London taxi was used as an iconic London image to secure the games and yet those same cab drivers are now being kicked in the teeth by Olympics chiefs over the VIP lanes and the entire Olympics transport strategy.”
However John Mason, Director of London Taxi and Private Hire, defended the arrangement.
"We have informed taxi drivers that any such demonstration is completely irresponsible and would only disrupt the travelling public – the very people taxi drivers are supposed to serve.
“We strongly urge taxi drivers to ignore calls to join these unnecessary protests and instead show why they are regularly voted the best in the world.”
