The trainer, who first won the Gold Cup with Double Trigger in 1995, added:
“Dee Ex Bee was the type of horse you dream of as a stayer. He had Group 1 quality, was tremendously versatile and ticked all the boxes physically.
“He competed against some of the very best horses around during his time in training and played his part in some tremendous races, including a Derby, Gold Cup at Ascot and a Goodwood Cup.
“I am delighted that he will have this opportunity at Arctic Tack Stud and have no doubt Irish breeders will benefit greatly from his presence.”
Mark Johnston, trainer of over 4000 winners including Double Trigger
