Daniel Ricciardo has been punished with a 10-second penalty following the French Grand Prix, promoting British teenager Lando Norris to ninth.
McLaren's Norris, battling a host of mechanical issues following a hydraulic failure, fell from seventh to 10th on the final lap after losing out in his duel with Ricciardo.
Alfa Romeo driver Kimi Raikkonen and Ricciardo's Renault team-mate Nico Hulkenberg then made their way past the stricken novice.
Ricciardo however, was later adjudged to have driven Norris off the road. The Australian was also punished for an off-track pass on Raikkonen during an action-packed last lap, ultimately demoting him to 11th.
"No regrets," tweeted Ricciardo in response to the penalty. "Would rather that than sit back without a heart."
Norris, who qualified a career-best fifth, had been on course to take the chequered flag in seventh, behind team-mate Carlos Sainz, before a technical problem in the closing stages derailed his fine display.
Indeed, the 19-year-old was voted by fans as the Driver of the Day.
The hydraulic failure affected Norris's steering, braking and gear changes.
"The car was unpredictable to drive because I had a whole load of problems which were not nice to have," said Norris.
"It cost us seventh. It is frustrating.
"I don't know how other people drove, but I will take the Driver of the Day award. I am over the moon with that.
"I did everything I could. I lost one place to Carlos off the line, but the whole day went very well, apart from the end and the problems we had."
