Uber has been stripped of its licence to operate in London after failing to stop unlicensed and uninsured drivers picking up thousands of passengers.

Uber was told it needed to address issues with checks on drivers, insurance and safety, but has apparently failed to satisfy the capital’s transport authorities. The decision is unlikely to see Uber cars disappear from London, as the firm is expected to appeal, and can continue to operate pending the outcome.

Transport for London (TfL) found that at least 14,000 trips were made with drivers who were different to the ones shown on the app.

This was due to a system change which allows unauthorised drivers to upload their photographs to legitimate Uber driver accounts, the transport body said.

It is clearly concerning that these issues arose, but it is also concerning that we cannot be confident that similar issues won’t happen again in future.’

Tfl said it had identified ‘several breaches that placed passengers and their safety at risk’ and ‘does not have confidence that similar issues will not reoccur in the future’.

It comes two years after Transport for London first tried to pull the plug on the firm’s operations in London, following a number of crimes committed by drivers.

The move sparked a mixed reaction among Londoners, with some saying they rely on the app to get them places cheaply.

Others were less sympathetic with the firm, saying they were shocked at the security risks.

The London decision is the latest in a string which has rattled shareholders and cast the company’s future into uncertainty.

Dara Khosrowshahi, who took over from Travis Kalanick as CEO in August, tweeted on Monday morning: ‘We understand we’re held to a high bar, as we should be. But this TfL decision is just wrong.

‘Over the last 2 years, we have fundamentally changed how we operate in London. We have come very far and we will keep going, for the millions of drivers and riders who rely on us.’
