Olympic gold medallist Carl Hester completed a title double on his London 2012 horse Uthopia at the National Dressage Championships in Warwickshire.
Hester, who won Saturday's grand prix class, backed it up by landing the Espayo Grand Prix Freestyle section with an emphatic victory.
The combination, part of Great Britain's Olympic title-winning team alongside Charlotte Dujardin and Laura Bechtolsheimer at Greenwich Park, scored 81.80%.
Bechtolsheimer and her back-up horse Andretti H were second on 76.58%, just ahead of Michael Eilberg and Half Moon Delphi with 76.35%.
