Outsider Rule The World produced a magnificent late burst to win the Grand National at Aintree on Saturday under teenage jockey David Mullins.
Favourite the Last Samurai looked poised to justify the money that came in for him by claiming victory the world's most famous steeplechase, but 33-1 shot Rule The World charged down the outside to pull off a shock triumph.
Mullins, riding in the famous race for the first time at the age of 19, produced a brilliant ride on testing ground for the Michael 'Mouse' Morris-trained nine-year-old gelding.
Morris won the Irish Grand National with Rogue Angel last month the popular Irishman was in the winners' enclosure again after a heroic staying performance from Rule The World, claiming a first victory over fences in the marathon race over four miles and two furlongs
The Last Samurai had attracted plenty of support to take favouritism from last year's winner Many Clouds, but was unable to match Rule The World's late burst and finished six lengths back in second.
The 100/1 shot Vics Canvas exceeded expectations to take third place, with Gilgamboa fourth as there was no record third win in a row for Leighton Aspell as Many Clouds - favourite this morning - made a mistake four out and was pulled up.
Seven-time Group One winner Silviniaco Conti dropped to the back of the field and pulled up before the halfway mark after the well-fancied Holywell was among the early fallers.
Sir Des Champs, ridden by Nina Carberry after her brother-in-law Ruby Walsh was ruled out due on Friday due to a fractured wrist, went soon after as Many Clouds continued on strongly at the front in his bid to make history.
The Last Samurai, ridden by David Bass and trained by Kim Baily, joined last year's winner out in front and went out on his own after Many Clouds made a blunder four flights from home.
But Rule The World charged to the front with an incredible late burst to claim a famous victory for Morris, whose son Christopher tragically died in Argentina last year.
Morris told BBC Radio 5 live: "This is just magic, I've got great friends who stood by me and helped.
"I'd have settled for third at the Elbow but he ran on like a train. He has injured his pelvis in two falls and before that he was one of the best horses I ever had."
