O`Brien threatens to leave Ireland Ballydoyle maestro Aidan O`Brien celebrated a one-two-three in the Budweiser Irish Derby then reiterated his threat to leave the unique training centre if plans to build an incinerator close by went ahead.High Chaparral enjoyed a virtual lap of honour as he became the third straight Vodafone Derby winner to follow up at the Curragh with a comfortable victory in the Budweiser Irish Derby.Like Sinndar and Galileo before him High Chaparral delighted the thousands of fans who defied the rain to turn out and welcome home the local hero in a race which turned into a personal triumph for Aidan O`Brien who also saddled the runner-up Sholokov and third-placed Ballingarry.But the trainer confirmed afterwards that he may sensationally quit the country if the controversial plans to build the incinerator come to fruition.'It is true,' said O`Brien, who is very worried by potential pollution problems.'It`s not fair to ask people to rear families in that sort of environment. And horses take in 40 times as many dioxins as human beings so that would be a big worry.'Asked about a possible new training base, he said: 'There are a lot of options - Coolmore has a big operation in America and that is defintely an option.'
