Transport for London (TfL) rejected the Silicon Valley company’s license renewal request in 2017 due to failings it said it found in its approach to reporting serious criminal offences and driver background checks, prompting legal action.

A judge in 2018 then granted Uber a probationary 15-month license, which expires on Sept. 25, after the company had made several changes to its business model in London, the firm’s most important European market.

A question put to London Mayor Sadiq Khan from a member of the city’s assembly about the license renewal is still awaiting a reply according to an entry on the London Authority’s website from earlier this week.

TfL said it does not comment on individual license applications. Uber declined to comment on Friday.
