Formula 3000 team owner Christian Horner is the new head of Red Bull Racing after the new team's senior management walked out this morning.
Horner, whose Arden International team dominated recent F3000 campaigns with the likes of Vitantonio Liuzzi and Bjorn Wirdheim, has today been named Red Bull's new sporting director.
The 31-year-old Briton inherits a team preparing for their first in Formula One since the demise of Jaguar Racing.
David Pitchforth and Tony Purnell had overseen the transition from Jaguar to Red Bull and were expected to lead the team throughout 2005. But they quit as team manager and managing director respectively this morning.
A Red Bull statement read: "Horner will jointly manage Red Bull Racing together with a new technical director, whose appointment will be announced within the next week."
Red Bull are still to decide whether Liuzzi or former Jaguar driver Christian Klien will partner David Coulthard this season.
