Apple COO Jeff Williams is retiring after 27 years. His exit marks another recent major leadership shift at the company.

Sabih Khan, an Indian-origin techie, has been appointed as Apple’s new chief operating officer (COO). The Moradabad-born executive has been part of the tech giant for nearly 30 years, and will succeed Jeff Williams.

Apple on Tuesday named insider Sabih Khan as its chief operating officer, taking over from Jeff Williams, as part of a long-planned succession.
