A motorcyclist who suffered serious head injuries after an accident during Sunday's World Superbike Championship at Brands Hatch has died.

Craig Jones collided with another rider after appearing to lose control and fall from his Team Parkalgar CBR600 Honda.

The 23-year-old from Cheshire was airlifted to the Royal London Hospital but died from his injuries early this morning.

Circuit boss Jonathan Palmer said: "I am so desperately sad. He was a really super young guy, so determined and professional.

"Britain has lost a wonderful rider who had every chance of being a future world champion."
