Paul Monaghan, Red Bull's chief engineer, says he won't skirt the Christian Horner topic as the Briton did "everything" for him and Red Bull.

A new Red Bull era begins under Mekies at this weekend’s Belgian Grand Prix. He was appointed after 18 months at Racing Bulls. He worked at Ferrari for five years, as deputy team principal and racing director, and at the F.I.A., which governs Formula 1, for four years, initially as safety director and then deputy race director.
