Christian Horner has been cleared by Red Bull of any wrongdoing after an investigation into their team principal over allegations of workplace misconduct made by a female employee.
The decision comes on the eve of the new season, following an independent investigation that involved an eight-hour meeting with Horner.
Horner, 50, has denied all accusations of inappropriate workplace conduct made against him by a female employee of the team.
In a statement Red Bull said the employee who made the allegation can appeal their ruling, but they believe the investigation has been thorough.
"The independent investigation into the allegations made against Mr Horner is complete, and Red Bull can confirm that the grievance has been dismissed," the statement read.
"The complainant has a right of appeal. Red Bull is confident that the investigation has been fair, rigorous and impartial.
"The investigation report is confidential and contains the private information of the parties and third parties who assisted in the investigation, and therefore we will not be commenting further out of respect for all concerned."
Dutch newspaper De Telegraaf first reported that Horner was being investigated by Red Bull GmbH, the parent company of F1 team Red Bull Racing, in early February.
The report stated a female employee had reported workplace misconduct against Horner to the parent company, which led to an independent investigation and involved an eight-hour interview with the team principal.
Later that month, De Telegraaf reported that the alleged behaviour involved sexual misconduct.
Horner has continued working in his role at team principal and CEO of Red Bull Racing since the allegations came to light, including being front and centre of the season launch.
The announcement comes at the dawn of the new F1 season, where Red Bull is looking to win a third constructive constructors' championship, and Max Verstappen is hunting a fourth drivers' championship on the trot.
Horner has guided the team to six constructors' championships and seven drivers championships (Sebastian Vettel 4, Max Verstappen 3), making them one of the most successful teams in F1's history.
He has been team principal of the Milton Keynes-based team since 2005, when Red Bull took over the team from Jaguar.
