Red Bull’s head of race strategy, Will Courtenay, will leave his role to join their Formula One rivals McLaren as sporting director, the Woking-based team said on Tuesday.

Red Bull have lost a number of senior employees, including the star designer and former chief technical officer Adrian Newey, who left the Milton Keynes-based team to join Aston Martin as their managing technical partner this month.
