Mayor of London Sadiq Khan said in a statement: "I want London to be at the forefront of innovation and new technology and to be a natural home for exciting new companies that help Londoners by providing a better and more affordable service. Among the issues it raised: how Uber deals with serious criminal offenses and its explanation for its use of a software program called Greyball that “could be used to block regulatory bodies from gaining full access to the app.”

The agency said it had concluded that the company was “not fit and proper to hold a private hire operator license.”

The decision can be appealed and Uber can continue to operate in London throughout the appeals process, a spokeswoman for Transport for London said. Transport for London said that it had rejected the US cab hailing app's application to renew its license because "Uber's approach and conduct demonstrate a lack of corporate responsibility" in relation to reporting serious criminal offenses, obtaining medical certificates and other issues. The current license expires on 30 September but Uber has 21 days to appeal and can continue to operate until that process expires, reports The Guardian. Mayor of London Sadiq Khan said in a statement: “I fully support TfL’s decision – it would be wrong if TfL continued to license Uber if there is any way that this could pose a threat to Londoners’ safety and security.”

General Secretary of the Licensed Taxi Drivers’ Association Steve McNamara: “The mayor has made the right call not to relicense Uber.”

“We expect Uber will again embark on a spurious legal challenge against the mayor and TfL, and we will urge the court to uphold this decision.
Transport for London announces that it will not issue Uber a new private hire license.
