Mercedes driver Kimi Antonelli has made Formula One history after becoming the youngest-ever world champion at the age of 20 years and 68 days.
The Italian secured the title on Sunday after finishing third in the Mexico City Grand Prix, which was won by Red Bull's Max Verstappen.
Antonelli's podium finish gave him an unassailable 119-point lead in the championship standings, making him the first Italian driver to win the title since Alberto Ascari in 1953.
The emotional youngster broke down in tears over the team radio as he crossed the finish line at the Autodromo Hermanos Rodriguez.
His race engineer, Peter Bonnington, congratulated him, saying: "Get in there, Kimi. Champion of the world."
Antonelli responded: "We did it, thank you so much."
His parents and sister were waiting to embrace him when he climbed out of his car, before being surrounded by his Mercedes team.
The race was marked by several dramatic incidents, including two safety cars, multiple crashes and a 33-minute suspension with 25 laps remaining.
Ferrari's Lewis Hamilton finished second after starting from pole position, while Verstappen claimed victory.
Speaking after the race, Antonelli said he was still trying to process the achievement.
"I'm speechless. I'm trying to process what has just happened," he said.
He described the season as incredible and said he was proud to share the podium with Verstappen and Hamilton.
Antonelli admitted that emotions nearly got the better of him during the final lap, revealing that he had slowed down because he was struggling to see the track through his tears.
Germany's Sebastian Vettel previously held the record as Formula One's youngest world champion, having won his first title at the age of 23 years and 134 days in 2010.
