British Racing Drivers' Club president Damon Hill says he's anxiously watching the progress of Donington, as he still thinks there are doubts the circuit will be ready to host next year's British Grand Prix.
Donington will replace Silverstone as the venue for the British race from next year, but the circuit's redevelopment plan has been surrounded by speculation that it may not be ready in time for the event.
Donington, however, has received all the necessary planning permissions and work was scheduled to start this month.
Speaking to AUTOSPORT on Thursday, Hill said the skepticism over Donington's plans has been justified, and he insists he is still unsure about whether the works will be completed on time.
"Well, I think there has been a lot of skepticism, and perhaps justified skepticism, of Donington's claim to be ready for 2010, and everyone's anxiously watching that space because it may be that there won't be a venue available to host the British Grand Prix in 2010," Hill told AUTOSPORT.
Hill also admitted he was not surprised by the shows of support from F1 members following this year's British Grand Prix at Silverstone
"No, I think everyone at Silverstone did a superb job," Hill added. "Richard Phillips should take an enormous amount of credit for managing that, but also of course we had in the last two years two British drivers in contention for the championship which helps put bums on seats.
"So We've enjoyed the fruits of their work as well. But the thought that the British Grand Prix could be in jeopardy because of ... let's call it a high-risk strategy is actually worrying, because Britain has shown over the years that it is one of the greatest supporters of grand prix racing and of motorsport in the world.
"So it doesn't seem to be right that there should be any doubt over that."
