Christian Horner must have breathed a sigh of relief when the Red Bull Racing team boss learnt that Jos Verstappen was passing up the British Grand Prix.

No doubt Horner would prefer to see Father Verstappen disappear from the picture completely, but that would be a vain hope. After all, Max - Red Bull Racing's star driver - is 100% behind his father.
