Having grown up together in the royal family, cousins Prince Harry and Zara Tindall have shared many experiences, but there's one that nobody else in the family has experienced.
Earlier in January, Zara played a polo match in Australia alongside Harry's close friend and professional polo player Nacho Figueras. Playing polo matches with Nacho is commonplace for Harry, as they're on the same polo team in California, but it's not something any other royals have experience in.

Prince William is fond of polo too, with Nacho praising the heir to the throne's polo prowess, but they are not believed to have actually played alongside one another.
Speaking of William and Harry's love of polo back in 2016, Nacho told HELLO!: "They love the sport of polo so it's always fun to be around them.
