Olympic gold medallist Scott Brash gained a podium finish on the opening day of the London International Horse Show's showjumping schedule at Olympia.
Brash, from Peebles in Scotland, finished second aboard Bon Ami in the Christmas Speed Stakes.
Their time of 52.41 seconds was just 0.38secs behind Swedish winner Peder Fredricsson and Holliday KLG, and hinted at a promising start to a busy five-day programme.
Brash helped Great Britain to Olympic team gold at London 2012.
All three of his colleagues at Greenwich Park - Nick Skelton, Ben Maher and Peter Charles - are also in action during an event highlighted by Saturday's Rolex FEI World Cup class that was won last year by Maher.
Maher finished fourth with Milena, clocking 54.73 seconds, while Essex-based Laura Renwick was third on Rollercoaster.
The Welcome Speed Stakes, meanwhile, went to France's Roger Yves Bost and Castle Forbes Cosma, with Renwick taking second spot on Oz de Breve.
Ireland's London 2012 individual bronze medallist Cian O'Connor captured the main evening class with victory in the Christmas Pudding Stakes.
Riding chestnut gelding Splendor, O'Connor comfortably won a seven-horse jump-off, beating Great Britain's Tina Fletcher and Hello Sailor by 2.5 seconds.
"You take chances you wouldn't normally take at this show," O'Connor said.
"After the turn to the double I thought 'Did I really do that?' But this place, and the fantastic crowds, make you do that."
Fletcher, back in action following a serious ankle injury, was thrilled with Hello Sailor's performance, a horse she is aiming at next year's European Championships in Denmark.
"I am chuffed to bits, it has been a long time out of the ring for me," she said.
