William Haggas, Approve's trainer, said: "Unfortunately we have to carry a Group Two penalty, so it means he has to give Elzaam 3lb, which will be difficult. He's a tough and genuine horse and I'm a firm believer that the more races he has, the better he is."
The field is completed by Godolphin pair Neebras and Marston Moor, who will be making his racecourse debut.
Sir Michael Stoute, who revealed yesterday that champion jockey Ryan Moore will continue the Derby-winning partnership with Workforce in the King George VI & Queen Elizabeth Stakes at Ascot on 24 July, saddles Spanish Moon in tomorrow's Group Two Princess Of Wales's Sportingbet.com Stakes.
Spanish Moon, who is also owned by Prince Khalid Abdulla, was last seen in action on these shores in November 2008 after some antics at the stalls.
Stoute's six-year-old has since proved himself well worthy of a place in any Group One event, having been placed in the last two Dubai Sheema Classics as well as finishing second in the valuable Hong Kong Vase.
He can now resume his career in England and France is also in the thoughts of his connections.
Lord Grimthorpe, the Prince's racing manager, said: "We're in the happy position of being blessed with some very good mile-and-a-half horses, so we're going to have to sort out which horses will go for the Prix de l'Arc de Triomphe [in October]. Certainly, Spanish Moon is a contender."
Spanish Moon meets seven rivals on his first appearance since going down by a length to Dar Re Mi in the Dubai Sheema Classic at Meydan in March.
