Hillier aheadpublished at 16:30 British Summer Time 18 May 2019
Bit of a messy start as Conor Cummins veers across the track but everyone gets on their way.
Seeley gets past Glenn Irwin over Primrose Hill then Irwin finds a slipstream to retake the lead... I suspect this battle at the top could be tight.
Oh look at James Hillier on his Superstock bike, comes flying up past Seeley and into second! That was powerful, and then he goes one better and moves in front of Glenn Irwin.
Hillier, Irwin, Seeley at the end of the first lap.
