O’Brien’s son, Donnacha, rode the horse to victory, defeating 50-1 shot Tip Two Win by a length and a half, with favourite Masar a further head adrift in third.

The 19-year-old winning rider said: “It’s very special, I’ve got to say a huge thanks to dad and the owners for giving me the chance to sit on him and hopefully I didn’t mess up today.

“He’s an absolute monster of a horse so you never know, he could improve again.

“I was very impressed, I thought he was a very good horse even on his homework, we’ve made no secret of it, and I think he’s very, very good.”
