The event marked the first time the cousins have been seen together publicly. William and Kate met their nephew, Archie, in mid-May at Harry and Meghan's Frogmore Cottage home in Windsor.

Meghan has been on maternity leave since Archie's birth, but stepped out for Trooping the Colour in June and made a private visit to Wimbledon last week to support her friend Serena Williams.

Harry and William are playing against each other in the charity match in honor of Leicester City chairman Vichai Srivaddhanaprabha, who was killed in a helicopter crash last year.
