Jamie van Sikkelerus took the win after a dramatic three-bike battle as Jack Scott lifted the GP2 title as he crossed the line seventh.
In a dramatic race where yesterday’s race winner crashed out early, it came down to a three-rider scrap between van Sikkelerus, Lee Johnston and Harry Truelove.
Johnston tried to sweep up the inside into the final corner but ran wide allowing van Sikkelerus to storm to his first series win, followed over the line 0.380secs by Truelove with Johnston third and a just 0.134secs further back.
Tom Booth-Amos took fourth with Luke Jones fifth as a thrilled Jack Scott celebrated GP2 race and title victory.
Mason Law was the second GP2 rider home in 12th place with Jake Archer third.
