Lewis Hamilton and Max Verstappen are both to be investigated after the Italian Grand Prix for the collision that saw the title rivals retire.

Verstappen had been running second to Daniel Ricciardo but suffered a slow pit stop, dropping him back behind Lando Norris on the road. Hamilton himself then came into the pits to try and jump Verstappen, and emerged alongside the Red Bull as they approached the first chicane.

Verstappen attempted to go round the outside of Hamilton but was squeezed towards the edge of the track, and the championship leader then went over the sausage curb on the apex of the second part of the chicane, launching him up on top of Hamilton’s car.

Race stewards will be reviewing the Hamilton/Verstappen incident after the race 👀
