The main event taking place on Saturday is the Irish 2000 Guineas, with Aidan O'Brien possibly fielding Paddington and Little Big Bear, while son Donnacha will be aiming for victory with Proud And Regal.

Thursday's Brigadier Gerard event, featuring last year's Derby winner Desert Crown, is a major highlight, along with Saturday's Temple Stakes at Haydock, marking The Platinum Queen's comeback since joining Roger Varian.
