Red Bull have waved the chequered flag to team principal Christian Horner.
The 51-year-old had been in the role since 2005, overseeing eight drivers' world championships and six constructors' titles.
The syndicate sits fourth on the teams' ladder this season, and four-time defending world champion Max Verstappen has won two of 12 races with reports suggesting he is considering a shift to Mercedes.
F1 Journalist Chris Medland told Heather du Plessis-Allan that while no definitive reasons have been given yet, there are multiple possibilities.
He says that the team’s form on the track has been in decline over the last 18 months, and Horner also faced controversy off the track during that time.
Verstappen’s future could have also been central to the decision, Medland says, with Verstappen also wanting to see change and not getting it under Horner’s leadership.
