Mercedes chief technical officer, James Allison, says the penalty Lewis Hamilton received for his collision in the British Grand Prix was “harsh”.

Allison says Hamilton followed Formula 1’s overtaking rules in the incident.

Hamilton was adjudged by race stewards to have been “predominantly to blame” for the incident at Copse corner, which resulted in Verstappen being taken to hospital after a 51G impact.

The seven-time world champion was given a 10-second penalty, which dropped him from second to fourth at his pit stop.

Hamilton recovered to pass Ferrari’s Charles Leclerc for victory with two laps to go and cut Verstappen’s championship lead to eight points.

Red Bull team principal Christian Horner angrily said “the move was never on”, and called Hamilton’s passing attempt “desperate”, “ill-judged” and “amateur”.
