Christian Horner is out as Red Bull’s F1 team boss after 20 years and eight titles. The team gave no reason for the midseason move — but it comes amid on-track struggles, Verstappen drama and past controversy.

Formula 1 team Red Bull Racing has fired Christian Horner as team principal and chief executive after 20 years in charge, the team said in a statement.

Speculation is swirling that Mercedes could swoop for Verstappen for next season onwards, with reports suggesting the Dutchman can use an exit clause to leave Red Bull if he lower than fourth in the Drivers' Championship by the summer break after the Hungarian Grand Prix at the start of August.
