If last months protest wasnt a big enough hint, Londons black cabbies are far from pleased with losing business to disruptive competitor Uber.

Transport for London (TfL) has plainly concluded the way Uber calculates fares using a mobile app is not the same as operating a taximeter, and is completely legal.
