Formula 1: Spa weather delays practice

The notoriously fickle weather in the Ardennes forest region forced a delay to the start of the penultimate practice session for the Belgium Grand Prix in Spa-Francorchamps this morning.

The session was due to begin at 8am British time but race officials three times put-back the start by 15 minutes because the low cloud cover meant the medical helicopters were unable to take-off.
