Aidan O’Brien pulls six out of Derby but still has 10 horses in £2m Classic

Trainer Aidan O'Brien, an 11-time Derby winner, has withdrawn six of his horses from the £2 million Epsom Derby but still retains 10 runners in the Classic. The field has been reduced to 22 horses ahead of the race, which is scheduled for June 6 at Epsom over a mile and a half. O'Brien remains a dominant force in the race despite the withdrawals.
