The new home of the British Grand Prix, Donington Park, has lost the rights to stage the British MotoGP from 2010, it has been announced.
As Silverstone in Northamptonshire relinquishes its Formula One claims, it is preparing to host the motorcycling event in a switch that has saddened Donington chief executive Simon Gillett.
Mr Gillett expressed "disappointment" at the loss, saying that since 1987 when the sport came to Donington, the circuit has invested a considerable amount of emotion and finance in MotoGP.
He added: "We would like to wish Silverstone the best of luck with the required construction and all of the work involved in staging a top flight motorcycle race and ask them to take care of an event that we have invested heavily in since we took it over with just 18,000 people attending each race."
But a separate statement issued by Donington Park revealed annoyance that the commercial rights holder for the sport, Dorna, did not "give the circuit the courtesy to renew the agreement, despite reassurances to the contrary".
The popularity of the motorcycle event has grown over the last decade, with over 70,000 spectators now regularly attending race day.
