Felipe Nasr took his first Cooper Tires British F3 International Series victory in a dramatic final race at Rockingham which was hit by a controversial incident on the opening lap.
Championship leader Jean-Eric Vergne clashed with both Carlos Huertas and Oli Webb on the run to Deene, with Huertas spinning off on the straight and Webb spinning at the hairpin. That triggered an incident behind that put a number of drivers out of the race, including Gabriel Dias and Daisuke Nakajima.
Nasr led behind the Safety Car but on the restart he was passed for the lead by Adriano Buzaid only to battle back ahead into top spot before pulling away at the front to take his maiden success.
A recovering Vergne was battling back up the order from fifth and got ahead of Buzaid into second place with the Brazilian also losing out to James Calado after losing time when he was forced wide by team-mate Jazeman Jaafar – who sustained a damaged wing and dropped back.
Buzaid took fourth despite another controversial moment when he forced Will Buller onto the grass exiting the Tarzan hairpin.
That dropped Buller back behind a recovering Webb although he reclaimed the position on the penultimate lap when he dived down the inside at Deene.
Webber was left with sixth place ahead of National Class winner James Cole and his title rival Menasheh Idafar.
Hywel Lloyd and Jay Bridger rounded out the top ten.
