Indian ride-sharing firm Ola says it has started registering drivers in London as it prepares to launch in the U.K. capital. The company, which is backed by Uber investor SoftBank, said it would look to launch its services in the city "In the coming weeks." The announcement comes just a day after Uber was stripped of its London license by the local transport regulator. London is Uber's largest European market, where it counts 45,000 drivers and 3.5 million passengers.
