Uber versus black cabs: Why are they arguing?
London black-cab drivers are planning to cause gridlock in the city to protest against car service Uber.
The Licensed Taxi Drivers Association argues that Uber's drivers are using a smartphone app to calculate fares despite it being illegal for private vehicles to be fitted with taximeters.
Action has been started by Transport for London (TfL) to secure a High Court ruling on the legality of the American company's app, which is growing in popularity in London.
BBC News got in the back of the cab to hear the views of black-cab driver Lloyd Baldwin, and Uber driver Ben John.
