Uber appointed a new boss for Britain and Ireland on Monday -- just over a month before its license expires in London.
The British capital is one of its most important global markets where the regulator has previously stripped it of its right to operate.
Transport for London rejected the company's license renewal request in 2017.
It was due to failings it said it found in its approach to reporting serious criminal offenses and driver background checks.
A British judge in 2018 then granted Uber a probationary 15-month license which expires on September 25th.
Melinda Roylett, former head of Europe at digital payment company Square, begins her new role at Uber on Monday.
The company has introduced several new initiatives in London to try to deal with regulator concerns--
including 24/7 telephone support and the proactive reporting of serious incidents to police.
