Donington Park's boss Simon Gillett has said he is disappointed with Dorna's decision to switch the British MotoGP race to Silverstone from 2010 for five years but has not criticised the MotoGP rights holders for making the change.

The deal to take the British Grand Prix to Silverstone next season was announced yesterday, amid rumours that the Northamptonshire track's owners, the British Racing Drivers' Club, paid double the race sanction fee shelled out by Donington.

"Given the need for a flagship event in 2010 to replace Formula One, we understand the importance to Silverstone of gaining the rights to MotoGP from a business perspective," said Gillett. "However, since 1987 we have continually invested in MotoGP, emotionally as well as financially.

"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.

"We are proud to have hosted the championship for 22 years and our continuing passion and enthusiasm for the sport will ensure that our commitment and dedication for staging this year's event will remain just as high. However, I'd also like to reassure the fans that we will still be staging world motorcycle racing at the highest level with our continued support of the Superbike World Championship.

"The ongoing growth of this burgeoning series with an ever increasing number of manufacturers and British riders will help to ensure that it provides close and exciting racing that should attract support and interest to equal that of MotoGP in Britain. We are also continuing our support of the British Superbike Championship and two-wheel club racing to prove our dedication and commitment at all levels of the sport."
