Christian Horner has been fired by Red Bull's Formula 1 team and it only adds to speculation about the future of four-time champion Max Verstappen.

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.

Martin Brundle has made a huge claim that the "Verstappen camp" at Red Bull contributed hugely to Christian Horner's sudden exit.
