FIA maintain silence on Christian Horner's future amid Red Bull investigation
Formula One's governing body, the FIA, said it will not comment on Christian Horner's future until Red Bull's investigation has been concluded.
But added 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.
A statement from the FIA on Monday read: "In relation to the independent investigation currently being undertaken by Red Bull GMbH, the FIA reiterates that until such time as the investigation has concluded and the outcome is known, we will not be commenting further.
"The FIA remains committed to upholding the highest standards of integrity, fairness and inclusivity within the sport."
Speaking at Red Bull Racing's car launch in Milton Keynes last Thursday, Horner, 50, insisted he would be in Bahrain for the opening race.
Horner said he was unable to provide a timeline as to when the investigation by the racing team's parent company, Red Bull GmBH, will be completed.
It is understood both Red Bull and Horner are keen for a swift resolution and sources have indicated to the PA news agency that there could yet be a conclusion by the end of the week.
However, it is thought unlikely that a verdict will be found before this week's three-day test in Bahrain which starts on Wednesday.
An F1 spokesperson said: "We have noted that Red Bull has instigated an independent investigation into internal allegations at Red Bull Racing.
"We hope that the matter will be clarified at the earliest opportunity, after a fair and thorough process, and we will not comment further at this time."
Last season Red Bull won all but one of the 22 races, with Max Verstappen taking his third world championship in as many years.
