Only five riders - all male - made it through to the second round in the class, which was restricted to ladies only until 2008. Drawn second last to go in the jump-off, Keith and Walk Tall II beat the time set by Geoff Billington, the only other rider to go clear, by just 0.3sec.
"This is our biggest win by far - to be honest, I was pleased with two clears so to win is a real bonus," said Keith, who finished second last month at Hickstead in the Bunn Leisure Derby Trophy.
Walk Tall II is a homebred 10-year-old by Kannan. "We bred four or five foals that year and he was always pick of the bunch," said Keith. "I may have to sell him on, but it would be nice to keep him for a while and enjoy him."
Hickstead-based Shane Breen is definitely enjoying a successful show, with the Irishman landing the Sky Sports Speed Classic on Ominerale Courcelle. It was the pair's second win this week, having won the Royal International Vase on Thursday.
Shane, who was last to go, knew exactly what he needed to do to win and he didn't disappoint, beating the leading time of fellow countryman Richie Moloney by more than two seconds.
It was an aggressive and tight-turning ride by the Irishman, who took huge risks that paid off handsomely. "I knew I could beat the time, and I took some strides out and saved some seconds so I could be a bit safer in a few of the trickier places," said Shane.
The Bunn Leisure Salver kicked off the International Arena action this morning at the Longines Royal International Horse Show, the official show of The British Horse Society. Belgian rider Rik Hemeryck and Papillon Z won, beating countryman Maurice Van Roosbroeck (Calumet) by 0.13 seconds.
"I first came to Hickstead 20 years ago and this is the first time I've been back since - it feels great to be back as it's a really nice show," said Rik, who worked for Peter Charles more than 20 years ago during a year-long stint in England.
Top show producer Robert Walker from Cheshire won the Garrick Engineering Shelters Ltd Supreme Hack Championship, with Royal Engagement, while Jayne Webber and Its After Eight won the Small Hunter Championship. Both will join the other champions for tomorrow's British Horse Society Supreme Horse title, while the pony winners will contest the Dick Saunders Supreme Pony Championship.
The pick of the crop in the fashion stakes today was our Ladies' Day winner, Philippa Butler from East Sussex. She was presented with her prizes by actress Barbara Windsor, a supporter of Variety, the Children's Charity.
"I knew it was ladies' day so I made an extra special effort, and it is so exciting to win," said Philippa, who wore a vintage replica of a 1950's polka dot dress with a matching floppy hat.
Judge Barbara Windsor praised the standard of the ten Ladies' Day finalists, and said: "Today is my first time at Hickstead, and it's lovely - you are seeing Britain at its best here."
