London is booting Uber out of the British capital city, the BBC reports.

It says Transport for London, the agency that oversees taxi services in the city, found Uber "was not fit and proper to hold a private hire operator license." and that the ride share firm's conduct "demonstrated a lack of corporate responsibility which could have potential public safety and security implications."

Uber says it will appeal. It has 21 days to do so.

Uber opponents have argued that the firm's cars increase traffic in a city already wrestling with too many vehicles on its streets and that it does not do enough to regulate its drivers.

About 3.5 million passengers and 40,000 drivers use the Uber app in London, the BBC says.
