BBC News: Epsom Derby: Aidan O'Brien has seven entries as he seeks record
The Irish trainer has Mogul, Russian Emperor and Vatican City among his contenders to tackle home hopes English King and Kameko on Saturday. He is set to saddle Love and Peaceful on the same day in the Oaks, where opponents include Frankly Darling.
A bumper weekend of racing action sees the return of Enable in the Coral-Eclipse Stakes at Sandown on Sunday. Rivals could include Coronation Cup victor Ghaiyyath and Royal Ascot winner Lord North. Frankie Dettori will ride Enable, having partnered Derby favourite English King and Oaks second favourite Frankly Darling on Saturday.
O'Brien's Derby squad is completed by Amhran Na Bhfiann, Armory, Mythical and Serpentine, although Armory and Mythical are also entered in Sunday's French Derby. He has decided not to run Santiago seven days after winning the Irish Derby, while Ennistymon and Passion complete his four-strong team in the Oaks, which has a total of 11 entries.
The Oaks and the Derby at Epsom - two of British racing's five Classics - are taking place behind closed doors and on the same day for the first time.
Three miles of fencing are being erected around the track, where public rights of way will be suspended for the day.
But racehorse owners - two per horse initially - will be able to start attending race meetings in England from Saturday in a "safe and risk-managed way", under plans agreed by the Racecourse Association, the Racehorse Owners Association and the British Horseracing Authority.
They will need to register before all meetings, arrive no earlier than 45 minutes before their first horse is due to run and leave the racecourse within one hour of the final race in which they have a runner.
There will be dedicated 'owner zones', which will separate owners from raceday workers, including trainers and jockeys, for infection control purposes, with no movement permitted between the two areas.
