Uber’s head of communications has become the latest executive to leave the embattled ride-sharing firm, BBC reports. 

Chief executive Travis Kalanick confirmed Rachel Whetstone’s departure in an all-staff email on Tuesday.

No reason has been given for her resignation, though it follows months of turbulence at Uber.

Ms Whetstone joined the company from Google in 2015. “I am incredibly proud of the team we have built,” she said in a leaving statement.

"Just as when I left Google, a strong and brilliant woman will be taking my place. I joined Uber because I love the product - and that love is as strong today as it was when I booked my very first ride six years ago.”

Jill Hazelbaker, who had deputized for Ms Whetstone, will take over. Uber would not say if the move would be immediate.
