By the time they had reached Surtees, Camier was back in the lead, Parkes having made an error to allow his rival through. With a clear track ahead, Camier promptly began easing out his advantage, pulling away to reach the chequered flag more than two seconds up on Parkes.
While Camier's win re-writes the history books, with nine races still remaining this season, he now has the opportunity to keep raising the bar as the series heads to Cadwell Park, Croft, Silverstone and Oulton Park.
He won't have the attentions of Parkes to deal with either, the guest World Superbike rider completing a brace of podium finishes for himself and the Kawasaki team having been the only man to get even remotely close to Camier throughout the weekend.
Away from the dramas taking place up front, the tussle for the remaining podium position was closely fought, with Ellison eventually prevailing. A positive end to a tough weekend for the Cumbrian, Ellison slipped to fifth at one stage, behind Muggeridge and Easton, but eventually emerged in front when he passed the latter at the half-way mark.
It meant Easton was denied the chance to make it three identical podiums in fourth position, the Scot unable to cling onto Ellison as the race wore on.
Having put in a strong initial effort, Muggeridge also began to fade, slipping into the clutches of the chasing pack, led by John Laverty.
Producing a fine ride from 12th on the grid, Laverty battled his way into contention with a series of passing manoeuvres, eventually relieving Muggeridge of fifth position on lap 14 to record another impressive result for the improving Buildbase Kawasaki team.
Muggeridge was forced to settle for sixth, ahead of Hill and Sheridan Morais, the South African again suffering from a bad start, but being able to claw his way back to eighth, his best result of the weekend.
Ian Lowry brought his troubled weekend to a close with a solid run to ninth, while Michael Rutter made it home tenth to make it four Kawasakis inside the top ten.
Outside the top ten, Steve Brogan crossed the line in 11th, ahead of Graeme Gowland, Karl Harris and Gary Mason, the latter mirroring Camier in winning all three Cup races on the Quay Garage Honda.
