"I want to be absolutely clear that there is a place in London for all private hire companies that play by the rules", Khan said.
The news comes just two days after Uber lost its license to operate in London over its 'lack of corporate responsibility.' The official transport regulatory body of London, Transport for London (TfL) declared Uber "not fit and proper" to hold a private cab operator's license.
TfL cited failures to report serious criminal offences, conduct sufficient background checks on drivers and other safety issues as grounds for not renewing Uber's licence. The company can continue operating "until the appeals process has been exhausted".
Uber, which has its headquarters in San Francisco, claims to have 3.5 million passengers and 40,000 drivers in the capital, who depend on the app for their livelihood.
"A blanket ban will cause massive inconvenience to millions of Londoners, all the while showing that the mayor of London is closed to business and innovation", he said.
TfL took the decision not to renew Uber's licence for security and safety reasons. "Please work with us to make things right".
In a sign of early political opposition to London's move, Greg Hands, the minister for London in the Conservative government, hit out at what he called a "blanket ban" on Uber.
On Friday, the TfL rejected Uber's application on the basis that the company was not "fit and proper" to hold a private auto hire operator licence after expiry of its current licence on September 30. Stop crying because UberEATS is safe A spokesperson for UberEATS has confirmed that the food delivery service would not be affected by TFL's decision.
The choice, which Uber intends to advance, raises the likelihood that different urban communities could be encouraged to take action against the organization.
London is likely one of Uber's biggest markets across the globe. They are saying that "TfL could have given the drivers a little bit more time because a lot of drivers are now out of work".
Uber has, however, announced a series of changes over the last few months to improve conditions for its drivers, including the introduction of in-app tipping and plans to increase some fees.
As Mayor of London I welcome innovative new companies that help Londoners by providing a better and more affordable service - but providing an innovative service is not an excuse for not following the rules.
