Apple names new chief operating officer

Apple has promoted Jeff Williams to the role of chief operating officer. Johny Srouji is also joining the company's executive team as senior vice president for hardware technologies.

"We are fortunate to have incredible depth and breadth of talent across Apple's executive team. As we come to the end of the year, we're recognising the contributions already being made by two key executives," said CEO Tim Cook.

"Jeff is hands-down the best operations executive I've ever worked with, and Johny's team delivers world-class silicon designs which enable new innovations in our products year after year."

Williams has been with Apple since 1998 and his recent duties included supervising the development of the Apple Watch.
