Red Bull design chief Adrian Newey is to leave the team in the wake of the controversy involving allegations about team principal Christian Horner.
Newey, regarded as the greatest Formula 1 designer in history, has told Red Bull he wants to move on, BBC Sport has learned.
The 65-year-old has been unsettled by the situation at Red Bull since Horner was accused of sexual harassment and coercive, abusive behaviour by a female employee, which Horner denies.
Red Bull and Newey did not immediately respond to requests for comment.
