Traffic chaos as taxi drivers bring London to a standstill in protest against Uber

Traffic chaos has descended upon central London as thousands of cab drivers take part in a mass protest.

Parts of the city are completely gridlocked after countless black cabs swarmed to Trafalgar Square to campaign against mobile phone app Uber.

Drivers claim the app is disrupting their business model.

Ironically Uber’s sign ups reportedly increased by 850% as a result of today’s protest.
