Saturday night is final night in this year's William Hill Greyhound Derby and there will be a new training name on the roll of honour as all six trainers bid for their first success in the world's greatest race.

Racing Post greyhound expert Jonathan Kay joins Mark Walton to look ahead to the action at Wimbledon, offering his thoughts in the final itself and the supporting card which contains the finals of the William Hill Derby Plate and the William Hill Champion Hurdle.

Jonathan offers his one-two-three predictions in each of the eight televised races and tells us who he thinks will be this year's Derby Champion.

Enjoy.
