The Prince of Wales was supported by his cousin, Peter Phillips, and his girlfriend, Harriet Sperling, as he played in a charity polo match, which managed to raise £1.1 million for organisations supported by the royal and his wife, the Princess of Wales.
Like his father, the King, William has been an avid polo player since his teenage years and the event marked the 14th time that he has played in this match. While William was in a defensive role for the match, he still managed to score one of the goals as his team clinched victory.
Commentator Carl-Ude-Martinez quipped that the shot "trickled in, it wasn't pretty but we'll claim that one".
The ten charities supported this year are: Child Bereavement UK, Royal African Society, Fields in Trust, We Are Farming Minds, Anna Freud Centre, Family Action, East Anglia's Children's Hospices, NHS Charities Together and British Red Cross.
The event is set to take the total amount raised to more than £14,000,000 for William and Kate's causes.
