Tom Booth-Amos has taken the win after a dramatic last lap of the Supersport Sprint race at Oulton Park.
Championship leader Ben Currie had led the whole race from pole position, but an error on the final lap let a charging Booth-Amos through to steal victory.
Currie, who had managed to hold off Booth-Amos for several laps, ran wide coming into Hizzy’s and was powerless to stop the Gearlink Kawasaki coming through, as Dutchman Jaime van Sikkelerus was lucky not to get caught out as Currie dropped back.
But the points leader was able to hold onto second place from van Sikkelerus, as Tom Toparis found a way past Luke Jones on the final lap to take fourth.
Currie’s main title rival, Rhys Irwin, was left with nil points after being taken out after an uncharacteristic mistake from Richard Cooper on lap seven.
Cooper appeared to lose the front of his BPE Yamaha after just passing Irwin’s Suzuki for third place, his bike skittling a furious Irwin and forcing him out of the race.
Cameron Fraser took the GP2 win, just ahead of team-mate Harvey Claridge as Harry Rowlings took third in class.
