Double Olympic dressage champion Charlotte Dujardin has been confirmed among the entries for next week's London International Horse Show.
Dujardin will be aboard her London 2012 horse Valegro for the Reem Acra FEI World Cup event at Olympia next Monday and Tuesday.
The Gloucestershire-based rider won individual Olympic gold at Greenwich Park, and she was also a member of Great Britain's triumphant team alongside Carl Hester and Laura Bechtolsheimer.
Olympia will be Dujardin's first appearance on Valegro since the summer, while Hester is also among an 18-strong field, riding his Olympic horse Uthopia.
The top 15 combinations from Monday's preliminary grand prix will go forward to the freestyle to music competition on Tuesday night.
Other contenders include Britain's Richard Davison, who rode as an individual in London and was British team reserve, plus Dutch riders Edward Gal and Imke Schellekens-Bartels.
