Frankie Dettori has won The Derby at Epsom for the second time in his career after riding to victory aboard pre-race favourite Golden Horn.
The three-year-old Colt finished three-and-a-half lengths ahead of Jack Hobbs, handing British trainer John Gosden a one-two finish.
William Haggas' 25-1 outsider Storm The Stars came in third and Giovanni Canaletto was fourth.
Much-fancied 10/1 shot Elm Park, victorious in the Racing Post Trophy at Doncaster last October, faded badly after a positive start to end up 11th.
"It is unbelievable. What a feeling. I cannot believe it," Dettori, who first won the event eight years ago on Authorized before being handed a six-month ban from horse racing in December 2012 in the aftermath of a failed drugs test, said.
"I did feel the pressure coming into it because it was up to me to mess it up. It is such a good horse. I am absolutely delighted."
Gosden added: "I thought Frankie dropped him out beautifully. The last thing I said was ride a cool race and he did that perfectly.
"Jack Hobbs ran a blinder and I thought it was a great ride from both of them. It's been a long journey and I'm delighted that we have done it."
