Aidan O'Brien goes for his eighth consecutive Dubai Duty Free Irish Derby, and 11th in all, at the Curragh.

The Ballydoyle handler is doubly represented in the Classic, but all eyes will be on Ruler Of The World, who maintained his unbeaten record in the Epsom Derby under a fine Ryan Moore ride.

Joseph O'Brien takes over in the saddle now, and his mount attempts to confirm his length-and-a-half superiority over Libertarian, who has been snapped up by Godolphin since his excellent Derby second, and third-placed Galileo Rock.

Trading Leather runs for Jim Bolger, but the chief home threat to the favourite could come from Sugar Boy, who had Libertarian and Galileo Rock in behind when landing the Sandown Classic Trial.

O'Brien's stranglehold on the Dubai Duty Free Railway Stakes has been loosened in the last few years, but he still holds all the aces, with Norfolk Stakes runner-up Coach House and vanquished Coventry Stakes favourite Stubbs flying the flag in the Group Two.

There is a strong raiding party from across the Irish Sea targeting the Woodies DIY Sapphire Stakes, with improving three-year-old Morawij and King's Stand seventh Move In Time possibly the pick.

But the Eddie Lynam-trained Slade Power also ran at Royal Ascot, occupying the same position in the Diamond Jubilee - with the reopposing Maarek behind him - and he will launch a bold attempt to keep the prize on home soil.

The Brits are also mob-handed in the valuable Paddy Power Sprint, with last week's beaten Wokingham favourite Gabriel's Lad bidding for compensation for Denis Coakley.

Caponata has never tackled a distance as short as a mile, but gets the opportunity in the Dubai Duty Free Millenium Millionaire Celebration Stakes, while Intensified's narrow Leopardstown second to War Command was boosted when the winner took the Coventry Stakes field apart, so he is sure to be a warm order for the opening Dubai Duty Free Finest Surprise EBF Maiden at 3.10.
