LEWIS Hamilton has no chance of being handed the Formula One world title unless McLaren can categorically prove their rivals cheated, according to Eddie Jordan.

Hamilton failed to become the sport's first rookie champion following a disastrous Brazilian Grand Prix yesterday but has seen his hopes resurrected after Williams and BMW were found to have irregularities with their fuel temperatures.

Had they been disqualified, Hamilton would have been elevated from seventh to fourth place, thereby denying Kimi Raikkonen the championship. But race stewards said there was sufficient doubt over the measurements to render a penalty inappropriate.

Hamilton's McLaren team have already confirmed they will appeal that decision.

But Jordan, founder of the eponymous F1 team that were purchased by Dutch car company Spyker two years ago, believes the evidence McLaren require to overturn the stewards' call cannot exist.

He said on Radio Five Live: "You've got to prove that the fuel that went into the car, at the time that it went into the car, was ten degrees lower than what the ambient temperature was."
