Hamdan Al Maktoum, successful in 1989 with Nashwan and in 1994 with Erhaab, has 37 entered, Maktoum Al Maktoum has nominated a further 32 with both Sheikh Ahmed Al Maktoum and Sheikh Obaid Al Maktoum having one entry each.
The Aga Khan, who has won the race four times, has 27 entries while Dubai-based Saeed Suhail, owner of last year’s winner Kris Kin, is responsible for 11 entries.
Sue Magnier has 32 entries, with all but one being trained by Aidan O’Brien while The Queen of England has six entries – four with Sir Michael Stoute and two with Roger Charlton.
There is a sizeable entry from across the Channel, with Andre Fabre having 20 horses engaged in the race.
“We are very grateful for the continued support of the Vodafone Derby from all the major owners but we particularly welcome the growing number of smaller owners and syndicates who have joined in pursuit of the Derby Dream and very much hope to see them and their horses on Epsom Downs in 18 months time,” said managing director Stephen Wallis.
