CABBIES brought central London to a standstill yesterday in protest against Mayor Boris Johnson giving mobile phone app Uber — a private-hire company — the green light.

Thousands of taxis blocked traffic around Trafalgar Square against the decision, which unions Unite, transport workers’ union RMT and the GMB have suggested subjects drivers to fraud and raises serious concerns around passenger safety. 

The unions believe that Google and Goldman Sachs backed Uber is breaking with the Private Hire Vehicles (London) Act.
