A rider and a marshal have died at one of Britain's most storied road races.

The Southern 100 takes place in the Isle of Man every year, but the event has now been cancelled following last night's tragedy.

Some of the biggest names in road racing, including Bradford's Dean Harrison, were down there to compete.

Qualifying had already taken place for the Senior Race, with Davey Todd taking top spot and Harrison fourth on his DAO Racing Kawasaki.

But a serious incident occurred during the final lap of last night’s practice session, involving two riders, a marshal and a spectator.

It was announced last night that there were two fatalities, and this morning an update confirmed it was one of the riders and the marshal who had been killed. No further details have been released.

In a statement released today, the Southern 100 said: "Following the serious incident that occurred during the final lap of last night’s practice session, the Southern 100 can confirm that the remainder of the event is now cancelled.

"The Clerk of the Course has taken the decision to cancel the remainder of the event due to the ongoing investigations and this continues to be the priority of the organisation."
