Ride-hailing app faces showdown in high court over whether its service breaches rules stating that only London black cabs can use meters

Uber’s running global battle with taxi drivers, politicians and legal authorities moves to London next week with a court hearing that could deal a blow to the ride-hailing app in one of its most successful markets.

The San Francisco-based company has 18,000 registered partners, or drivers, in the UK capital. But that growth could be checked in the high court on Monday when London’s transport regulator, Transport for London (TfL), asks a judge to decide whether Uber is breaking the law.
