An F1 insider has opened up about an alleged heated argument between Christian Horner and Max Verstappen's father.

Christian Horner appeared to break down in tears as he delivered an emotional speech to Red Bull staff following his shock sacking. Horner addressed his staff at a speech captured by Sky Sports on Wednesday (9 July).

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.
