The Princess of Wales was pictured cheering from the sidelines as the Prince of Wales competed on a baking hot polo pitch for a charity cup.
William rode alongside top professional players and keen amateurs at the Guards Polo Club in Windsor Great Park.
It is thought just over £1m was raised on Friday as part of the DMMI Royal Charity Polo Cup.
William’s squad included former England captain Mark Tomlinson, Saudi businessman Amr Zedan and Leicester City FC chairman Aiyawatt Srivaddhanaprabha.
