Ferrari Formula 1 academy driver Giuliano Alesi has won his first GP3 race at the Silverstone sprint event after leading all 15 laps.
Alesi, son of ex-F1 winner Jean, led from the front row of the grid after being left alone as polesitter and Trident team-mate Dorian Boccolacci was stuck in the pitlane and unable to start.
He held on to triumph by 0.7 seconds despite pressure from behind from Renault-backed Jack Aitken, who found his way from fourth on the grid to second.
The Frenchman is the fifth winner of the 2017 season, with Trident becoming the fourth team to claim a victory.
Red Bull rookie Niko Kari held off championship leader and Mercedes junior George Russell to take a maiden podium in third.
Haas development driver Arjun Maini was fifth, with Alessio Lorandi sixth and Kevin Joerg seventh.
ART’s Anthoine Hubert completed the points finishers, finishing 8.4s behind the winner.
Haas’ other development racer Santino Ferrucci was ninth, missing out on points by 2.2s.
Sauber’s Tatiana Calderon and Honda protégé Nirei Fukuzumi finished as the final two classified runners in 15th and 16th.
The Japanese received a 10-second time penalty for overtaking under a safety car period.
