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, which was won by William’s team.

His squad included former England captain Mark Tomlinson, Saudi businessman Amr Zedan and Leicester City FC chairman Aiyawatt Srivaddhanaprabha.

Commentator Karl Ude Martinez told the crowd of the Royal Family’s polo legacy and how William and the Duke of Sussex used to compete together.

“His father played, King Charles got up to a very good handicap – their grandfather played, the late Duke of Edinburgh, Prince Philip, he played for many, many years and competed in many a big tournament,” he said.

“Their father before that played. They’ve played for many, many generations and it is something that is very close to their heart.”

Martinez added: “[William] has played for many years but he doesn’t often get time to play.

“He doesn’t get time to play at all, really, because of his commitments and his busy schedule.

“To have him here today to play is truly a very, very rare occasion.”
