Formula One supremo Bernie Ecclestone says next month's inaugural South Korean Grand Prix is at risk because the circuit has yet to pass a final inspection less than a month before the race.
Cancellation would have a major impact on the title outcome, with five drivers currently separated by just 25 points with a maximum 100 to be won - assuming South Korea remains on schedule.
The South Korean race is due to take place on October the 24th, with the final inspection repeatedly pushed back by the governing International Automobile Federation.
The FIA race director Charlie Whiting was due to visit the Yeongam circuit last month, but that was postponed, and the visit was again put off on his way to Singapore.
That has now been further delayed with reports suggesting it might not happen until the Japanese Grand Prix, a mere two weeks before the Korean race.
