Uber taxi boss defends new app

11 June 2014 Last updated at 11:31 BST

Transport for London (TfL) is allowing the taxi service Uber to operate "outside of the law", Steve McNamara from the Licensed Taxi Drivers' Association has said.

His comments come as taxi drivers gear up to protest against Uber's use of a mobile app to work out the cost of rides.

They argue this is tantamount to a taxi meter, which only black cabs are legally entitled to use in London.

But Jo Bertram, UK and Ireland general manager at Uber, argued that TfL should be allowed to create their own definition of what constitutes a taxi meter.
