Rolls-Royce's CEO Rishton to retire, Warren East to succeed
East, who has been a non-executive director of Rolls-Royce since January 2014, was chief executive of ARM between 2001 and 2013, and oversaw the growth of the Cambridge-based firm into a leading developer of chips for companies like Apple.
Rishton, who stands down on July 2 to seek a change in lifestyle, has been chief executive of Rolls-Royce since 2011, overseeing a difficult period for the company.
