The start of the Belgian Grand Prix has been delayed, as a result of heavy rain conditions at the Spa-Francorchamps circuit.
The race was scheduled to set off at 15:00 local time, but heavy rain has forced FIA Race Director Michael Masi to push out the start.
The formation lap has now been tentatively scheduled for 15:25 local time, as conditions continue to be monitored.
Sunday has been damp throughout, with support races taking place on a track generating a lot of spray due to the standing water. However, the rain picked up in intensity approaching the original F1 race start time, with visibility poor around the entire circuit.
The conditions have already caught out one of the drivers, with Red Bull driver Sergio Perez crashing on his way to the grid.
