Statement by McLaren team principal Andrea Stella:

“During the race, both cars experienced unexpected, high levels of porpoising not seen in the Practice sessions, which led to excessive contact with the ground.

We are investigating the reasons for this behaviour of the car, including the effect of accidental damage sustained by both cars, which we found after the race, and that led to an increase of movement of the floor.

We apologise to Lando and Oscar for the loss of points today, at a critical time in their Championship campaigns after two strong performances from them all weekend. As a team, we also apologise to our partners and fans, whose support means so much.”
