New Approach gave Irish trainer Jim Bolger and jockey Kevin Manning their first success in the Vodafone Derby with a game victory at Epsom.
The English and Irish 2000 Guineas runner-up, sent off at 5-1, just held the persistent challenge of Sir Michael Stoute's Tartan Bearer (6-1), ridden by Ryan Moore, by half a length
Another Irish runner, Casual Conquest, the 7-2 favourite, was four and a half lengths away in third.
Alan Devonshire and Bashkirov were quickly away but it was the rank outsider Maidstone Mixture who made the running as the field settled down.
Once the latter's moment of glory had gone it was Bashkirov who went on before Kandahar Run hit the front ahead of Doctor Fremantle as the runners approached Tattenham Corner.
But the pack soon closed in when they straightened up and Tartan Bearer made his bid two furlongs out.
Meanwhile, New Approach had moved up from the rear as Manning switched him from the outside to the far rail.
The race was between New Approach and Tartan Bearer in the final furlong and it was last season's champion two-year-old who stayed on the stronger to land the ultimate prize for owner Princess Haya of Jordan, wife of Sheikh Mohammed.Reuse content
