Jack Kennedy took victory over Ben Currie in the Feature race at Snetterton, as the race was cut short by two laps when rain began to fall.
The race was a battle between the reigning and former champion from the start, as the pair took turns at the front.
The lead swapped between the pair several times, with Kennedy leading for a few laps mid race before Currie hit the front on Lap Eight. But Kennedy was soon back ahead and although Currie was right on his rear wheel, he didn’t get the chance to pass again as the race was flagged on lap 10.
Luke Stapleford was third, ahead of Harry Truelove, as Alastair Seeley crossed the line fifth.
It was another GP2 victory for Owen Jenner, again ahead of his Kramer team-mate Jack Nixon, as Keo Walker was third.
In the Cup, Cameron Hall rode an impressive race to take the spoils, finishing 12th overall as Harry Cook was second and Lynden Leatherland third.
