Rain threat to Belgian Grand Prix

FORMULA One’s top drivers will not race in the Belgian Grand Prix if Spa-Francorchamps suffers any more torrential rain, they claimed amid fears over their safety on a wet track.

The race’s second practice session was washed out due to a continuous downpour which left rivers of water streaming across the Spa track in Belgium’s Ardennes forest.

Only three cars left the pits during the one-hour session - and one of those never made it back.
