Harry Charlton is excited to see his Royal Ascot runner-up King’s Gambit step up in class for the Sky Bet York Stakes on Saturday, with Callum Shepherd booked to take the ride for the first time.

A facile winner of the London Gold Cup on his three-year-old debut, the Saxon Warrior colt then charged home from an uncompromising position to finish second to Jayarebe in last month’s Hampton Court Stakes.
