US ride-sharing app Uber is not going down without a fight.

The company has filed its appeal against a decision by London authorities not to renew its licence.

“We have this morning filed our appeal on the London licence decision at Westminster Magistrates’ Court,” Uber said in a statement.

In September, Transport for London (TfL) refused Uber a new private hire licence, saying the ride-hailing firm was not fit and proper.

TfL said it took the decision on the grounds of "public safety and security implications".

The appeal process could take months, during which time Uber can continue to operate in London.

"While we have today filed our appeal so that Londoners can continue using our app, we hope to continue having constructive discussions with Transport for London. As our new CEO [chief executive] has said, we are determined to make things right," an Uber spokesperson said.

Earlier October, Uber's new chief executive Dara Khosrowshahi met Mike Brown, who runs Transport for London.

Uber described those talks as "constructive", while TfL said the talks "centred on what needs to happen to ensure a thriving taxi and private hire market in London".
