McLaren sporting director Sam Michael is leaving the Formula One team at the end of the current season to return home to Australia after 21 years in the sport.
Former Lotus Formula One team principal Eric Boullier is joining McLaren in the newly created role of Racing Director, with Ron Dennis in overall control.
McLaren showed off their new Formula One car on Friday with neither a title sponsor nor a team principal in sight but plenty of determination to banish the gloom of a depressing 2013 season.
The return of former principal Ron Dennis to a more hands-on role at McLaren will boost the hurting Formula One team this season, Jenson Button said on Friday.
