FORMULA ONE’S governing body, the International Automobile Federation (FIA), said it will not comment on Christian Horner’s future until Red Bull’s investigation has been concluded, saying it “remains committed to upholding the highest standards of integrity, fairness and inclusivity within the sport.”

Horner’s role as Red Bull team principal remains in the balance following a claim of “inappropriate behaviour” by a female colleague. Horner emphatically denies the allegations.

On Sunday, F1 bosses called for the controversy to be “clarified at the earliest opportunity.” The new season gets under way on March 2.
