The Silverstone circuit has announced a million dollar profit for 2008.

Vying to retain the British Grand Prix next year amid new venue Donington's reported troubles, managing director Richard Phillips said: "We remain one of the few venues in the world that produce a small profit from our blue riband event."

Meanwhile, there are frantic efforts at Donington Park to beat Bernie Ecclestone's Friday deadline to remedy its breach of the 2010 GP contract.

A spokeswoman for the local Derby Telegraph said an announcement on Friday is likely, with boss Simon Gillett "optimistic" in his attempt to attract enough eleventh-hour investors to fund the circuit renovation.
