An outstanding performance from Offaly's Darragh Kenny and the 12-year-old gelding Eddy Blue saw them take victory in Sunday's five-star Longines FEI World Cup Grand Prix at the London International Horse Show.
Just five of the 37 starters managed to jump clear in the opening round, with Kenny second to go against the clock.
A breathtaking round from the Irishman saw him stop the clock clear in 34.76 seconds. All those who followed, including a trio of British riders failed to beat the target to leave Kenny as the winner.
The result completes a hat-trick of Irish wins this week at London International, with Kenny also guiding Chaccossini to victory in Friday's Christmas Tree Stakes, while Derry's Daniel Coyle and Incredible were winners of Saturday's Longines Christmas Cracker.
On Saturday, Daniel Coyle and the aptly named gelding, Incredible, took victory in the five-star Longines Christmas Cracker.
Paris Olympian Coyle and the Ariel Grange-owned grey were second to go in the 13-horse jump-off, and set what proved to be an unbeatable clear in 30.52 seconds.
Many of those who followed tried in vain to catch the world number 12, including home favourite Ben Maher, who came closest and would finish as runner-up with Enjeu de Grisien in 31.52, while another British rider, Robert Whitaker, finished third aboard Gentlemen vh Veldhof.
A jubilant Coyle said: "This show last year was so fast and so much fun, all my friends and family are here, so I really want to do well, and I really enjoyed tonight."
Talking about his horse, Incredible, the Derry native continued: "I haven't even had him a year yet, so I’m still getting to know him, but he won a FEI World Cup Qualifier almost immediately after I got him, he’s done some Nations Cups this year, but it will be this time next year before I know everything about him and I’m trying to learn as much as I can, whilst doing this at this level, which isn’t easy, but he’s a good horse."
