Christian Horner, the longest-tenured team principal in Formula 1, is out after two decades. Here's what he told the team.

Laurent Mekies, the boss of sister team Racing Bulls, will replace Horner, who has been with the team since its inception in 2005 and led it to 124 wins and numerous championships.

Red Bull has pledged not give up on the Formula 1 title fight until it's mathematically impossible for Max Verstappen to win, even after Christian Horner was fired as team principal.
