The head of Uber's food delivery service in Europe, Middle East and Africa has become the latest to quit the troubled ride-sharing firm.
Jambu Palaniappan left his post as UberEats' regional manager for markets including the UK to join a venture capital firm on 30 November, Sky News reported.
Palaniappan joined Uber in 2012 and helped build its riding business in 60 countries.
He confirmed his departure from the company in a memo circulated to UberEats staff.
"When I joined this company in 2012, Uber was just a small start-up with 75 employees focused primarily on the US," the letter reportedly said.
"While I learned so much about how dynamic and unique cities and countries around the world are, I also learned that technology can be a powerful equaliser, bringing mobility opportunities and economic empowerment from Johannesburg to Cairo to Lahore, and magical food deliver experiences from London to Warsaw and beyond."
Similar to Uber's taxi service, UberEats is an online meal ordering and delivery service that connects customers with restaurants in dozens of cities around the world.
Uber has faced months of negative press over its corporate culture. Its former chief executive Travis Kalanick resigned in June and was replaced by Dara Khosrowshahi.
