Ben Maher won the Kingsland Christmas Tree Stakes and the Christmas Masters at the London International Horse Show at Olympia.
The British Olympic gold medallist guided Milena to victory in the one-round speed class before claiming the Christmas Masters after a jump off on Tripple X III.
The two wins ensured Maher maintains his top spot in the leading rider race.
Olympic bronze medallist Cian O'Connor won the Santa Stakes earlier on Friday.
Maher won the Christmas Cracker and Christmas Puissance on Thursday, although the latter does not count towards the leading rider race.
The British rider, who won team jumping gold at London 2012, clocked 48.56 seconds in the Kingsland Christmas Tree Stakes, with second-placed Germany's Marcus Ehning and Campbel finishing in 49.99 secs.
O'Connor was third on Ishd Dual Star, Britain's John Whitaker on Argento was fourth and Peter Charles, who was one of Maher's gold medal-winning team-mates, was fifth on Murka's Nevada.
Maher then took a thrilling win in the jump-off of the Christmas Masters by clocking 22.30 to beat Frenchman Roger Yves Bost, who posted a stunning clear round with Castle Forbes Vivaldo in just 22.50.
The double victory will give Maher confidence ahead of Saturday's FEI World Cup qualifier.
Irishman O'Connor and horse Splendor followed up Wednesday's Christmas Pudding Stakes victory by taking the Santa Stakes in impressive fashion.
They were more than a second clear of runner-up Penelope Leprevost and her horse Nice Stephanie.
"This little city has been lucky for me this year," said O'Connor.
"It's always great to win any class, but hearing your national anthem in London is very special."
O'Connor lost his 2004 Olympic Athens gold after his horse failed a drugs test and he served a three-months ban, but he won bronze eight years later at London 2012.
His two victories this week see him move into eighth place in the race to become Olympia's leading rider of the show with just over three days' competition left.
Portugal's Luciana Diniz finished third with Fit for Fun, while leading British contender Michael Whitaker and 2012 Olympic gold medallist Nick Skelton finished fourth and fifth respectively.
Elsewhere, Cheshire teenager Emily Ward producing a stunning performance to win the Team Murka and World Class Programme Under-23 British Championship.
The 13-year-old became the event's youngest winner, riding Witch to a jump-off time of 38.69.
"I am overwhelmed with how well the horse jumped," said Ward, who lives in Neston.
