Millions of Uber customers in London were tonight waiting to find out if they can use their favourite minicab service this weekend.
The controversial taxi-app firm has been set a deadline of 4.30pm tomorrow to file an appeal to the High Court - or go out of business in the capital.
The company was last month refused a new licence by Transport for London on the grounds it was not a 'fit and proper' operator.
Around 3.5m Londoners are said to use Uber. An estimated 40,000 drivers rely on the company for their livelihoods.
Uber's global CEO Dara Khosrowshahi last week met Transport Commissioner Mike Brown to try to 'make things right'.
The company hopes further talks will persuade TfL to renew its licence.
Uber lawyers are expected to formally lodge an appeal tomorrow to allow its drivers to continue operating in London until the courts make a final decision.
