Aidan O'Brien claimed his fifth victory in the Darley Irish Oaks, but it was Seventh Heaven and not odds-on favourite Even Song who came out on top.

Their stablemate Pretty Perfect took them along but was passed by Epsom runner-up Architecture halfway down the straight.

Seventh Heaven (14-1) was hot on her heels, however, and moved past under Seamie Heffernan to triumph by two and three-quarter lengths, with Harlequeen third and Even Song never a factor.

O'Brien's Peace Envoy (3-1) collected Group Three honours in the Jebel Ali Racecourse & Stables Anglesey Stakes.

The Darley European Breeders Fund Maiden has thrown up some top-notchers in recent years and Arcada (13-2) added his name to an illustrious roll of honour that includes Teofilo, New Approach, Sea The Stars and Australia by inflicting a half-length defeat on Capri

Helen Mooney was seen to good effect on Zeftan (14-1) to claim the Boodles Ladies Derby Handicap, while Have A Nice Day (13-2) repeated his victory of 12 months ago in the Killashee Handicap.

Queen's Vase third Twilight Payment was a warm order for the Kilsaran International Maiden but had to battle to see off Ex Patriot
