Charles Milesi secured his maiden Formula Renault Eurocup win in the second race of the weekend at Silverstone, as team-mate Logan Sargeant made it an R-ace GP one-two.
Lorenzo Colombo was provisionally set to start from pole position after a late lap in qualifying propelled him to the top of the order. However, this lap was later invalidated after the stewards found he had exceeded track limits at Stowe.
As a result, series rookie Milesi inherited pole. After successfully retaining first place at the start, building a 0.6-second lead by the end of the opening lap, he eventually stretched his advantage over Sargeant.
With his lead at two seconds with 10 minutes to go, Milesi maintained the gap until the chequered flag.
Sargeant matched his race one result by finishing second, while championship leader Yifei Ye extended his points advantage with a fifth podium in six races by finishing in third.
Christian Lundgaard, who had entered the Silverstone round as the points leader, ended up sixth. He carried a three-place grid penalty into qualifying and started the race from fourth.
After maintaining track position at the start, Lundgaard was increasingly under pressure from team-mate Max Defourny, and at mid-distance, Defourny dived to the inside of his Lundgaard at Vale to move up to fourth.
Three corners later, Oscar Piastri further demoted Lundgaard to sixth.
Finishing in seventh was Victor Martins ahead of Alexander Smolyar in eighth. Colombo, who started 13th after his pole time was deleted, climbed up to ninth.
Alexander Vartanyan and Richard Verschoor had battled for ninth in the opening laps, and despite losing track position, their duel continued. They finished 11th and 12th respectively.
The pair were beaten to the final point by Raul Guzman, who secured his first top 10 finish of the season.
Race one polesitter and winner Max Fewtrell started the race in 14th after a qualifying session in which he was 0.7s slower than his Saturday benchmark. He tumbled down the order as the race progressed, eventually trailing home in 26th.
