Tensions between title rivals Lando Norris and Oscar Piastri reached a new high as their McLaren team clinched the team title at the Singapore Grand Prix.
Norris slid into Piastri while passing him at the initial turn at the start of the race, leading the Australian to state it was "not fair" the team did not instruct them to reverse positions.
The controversial moment that is likely to cause problems at McLaren came as Norris dived down the inner line of Piastri after making a good start from fifth on the grid.
Norris was surprised by Verstappen decelerating more than he anticipated in the middle of Turn Three.
Norris touched the Red Bull, damaging the McLaren's front wing endplate, and that caused him to deflect side-on into Piastri, whose pace was disrupted, enabling Norris to gain position into third place.
Piastri said over the radio: "That wasn't very team-like, but sure."
Moments later, he added: "Is it acceptable that Lando just barging me out of the way?"
His engineer replied that the team were "looking at it", before coming back to tell Piastri that they would take "no immediate measures" in the race because "Lando had to avoid Verstappen" and that they would "review it afterwards".
George Russell dominated the race at the front on his way to a commanding victory, very much in the manner of his victory in Canada back in June.
Verstappen chose to start the race on soft tyres rather than the mediums on most other cars in the leading group, but the strategy did not pay off and Russell easily held the lead at the beginning before building a comfortable lead.
"It was slippery, but that's motorsport. I took the inner line, had a small correction but nothing more than that. It was hard but fair competition." - Lando Norris
Mercedes' rookie Kimi Antonelli took fifth place, overtaking Ferrari's Charles Leclerc on the fifty-fourth lap as the Ferrari lost performance, and then holding off Lewis Hamilton in the closing laps.
Fernando Alonso drove an excellent race to take P8 as the top performer outside the leading teams.
The Spanish driver and Racing Bulls' Isack Hadjar fought a brief battle in the opening stages, Alonso passing Hadjar into the first corner to take eighth, before the Frenchman got him back later in the lap, only for Alonso to pass again on lap three.
