James Ellison has scored a career first ViSK.com British Superbike victory in the second race of the day at Donington Park after capitalising on a mysterious delay for Leon Camier.

Having taken his first podium of the season with second place during the first race, Ellison would prevail in a tight early fight between himself and a number of otgher riders vying for a maiden BSB win before pulling out a comfortable advantage by the chequered flag.

In a race that was red flagged after just one lap initially when Karl Harris' Hydrex Honda dropped fluid down the length of the home straight before crashing, four riders would share the lead over the course of the restarted race.

Bumped up to the front row in the absence of Sylvain Guintoli, it was Walker who got the best start of the front row sitters, scything into the lead ahead of Richards and pole sitter Camier.

Having endured a fairly quiet opening race, Richards made his first appearance in front by the end of the lap when he planted a move on Walker at McLeans, a position he would cling on to for the next four laps.

In that time, Camier's challenge would falter, the Airwaves Yamaha slowing down suddenly at it rounded the Melbourne hairpin. However, somehow he was able to get it going again, albeit having lost almost 25 seconds to the leaders.

It meant Richards led, ahead of Walker, Ellison, Easton, Simon Andrews and Julien Da Costa, with only Walker of the sextet having previously won a race - albeit nine years ago.

Inspired by the opportunity to fight for victory, Walker snatched the lead back off Richards on lap five with a brave move at Goddards. Furthermore, he'd resist a challenge by Easton just a lap later, the pair swapping positions first at the Esses before Walker resumed the position by Melbourne.

Keeping a watching brief in third having overtaken Richards, Ellison duly pounded on Easton for second on lap seven with a move at McLeans before needing just one further lap to dispatch Walker having stalked the 'Stalker' through the Craner Curves and planting the move at the Old Hairpin.

It would be the decisive move of the race, Ellison taking the opportunity to blunt his rivals' response by pumping in a series of quick laps to put air between himself and Easton, who followed Ellison through on the same lap at the Esses.

Indeed, Ellison was untouchable, Easton's attempts at catching him again being stymied by the constant attentions of Walker, who maintained a presence in third for the remainder of the race.

It meant Ellison would come home a comfortable 2.5secs up on Easton to be crowned a BSB winner for the first time, ahead of Easton, scoring his second podium of the day, and Walker, who too is making his first appearance on the BSB podium for some time.

Although they fell away from the fight for the podium, the tussle for fourth was equally tense, with Richards - who dropped to sixth - catching and passing both Da Costa and Andrews, only for the latter to snatch the position back with a last gasp move on the final corner. Fourth represents the MSS Colchester Kawasaki rider's best ever BSB result.

Having lapped at the pace of the leaders briefly, Da Costa dropped back rapidly in the final few laps to go from fourth to 11th, being caught and passed by Ian Lowry and Cup winner Gary Mason, who crossed the line sixth and seventh.

Buildbase Kawasaki produced a welcome double top ten with John Laverty ahead of Tristan Palmer in eighth and ninth, while Graeme Gowland completed a good day for Rob Mac Yamaha to claim tenth.

Camier, meanwhile, put in an immense charge to rise up from 25th position to finish 12th and snatch three points for himself.

Elsewhere, having missed the first race following his part in the accident that involved Guintoli, Joshua Brookes would crash out of contention on lap eight, while Karl Harris was also out of the points after hitting problems on the final lap of the race.
