Summer traditionally indicates the start of the polo season for the royals. The late Duke of Edinburgh and King Charles both played polo in their younger years, while the Prince of Wales and the Duke of Sussex still like to compete in charity cup matches.
The action on the sidelines is just as lively and the Princess of Wales has been pictured in the past running after her three children, Prince George, Princess Charlotte and Prince Louis, as they watch their dad William play. Kate has been her husband's biggest supporter at the polo since their university days.
Kate will be cheering on William, as he takes part in the Out-Sourcing Inc. Royal Charity Polo Cup 2023 at Guards Polo Club on Thursday 6 July.
The match will be played to raise funds and awareness for 11 charities supported by The Prince and Princess of Wales: Mental Health Innovations, Wales Air Ambulance, Centrepoint, The Passage, Mountain Rescue England & Wales, Foundling Museum, Forward Trust, East Anglia Children’s Hospices and Baby Basics, Little Village, AberNecessities.
In recent years, we've also seen Meghan Markle cheer on her future husband Harry in 2017, before they made their official debut as newlyweds at the polo the following year and in 2019, as parents with baby Archie.
Take a trip down memory lane with the best photos of the royals at the polo.
William and Kate shared a rare PDA as the Prince played in the Out-Sourcing Inc. Royal Charity Polo Cup 2022 at Guards Polo Club. The Princess looked stunning in a white midi dress by Emilia Wickstead and statement earrings for the occasion.
