As one of the royal family’s fondest sporting traditions, it is an unlikely front in the battle for gender equality. During a polo match, the Duke of Cambridge, Prince Harry or previously the Prince of Wales would grace the pitch while their wives watch on patiently, occasionally handing trophies to the victors.

But the roles of men and women should be reversed, according to the world's best female polo player, who argues that more female royals should take up the sport. Nina Clarkin, the British polo player who is the only woman in the world to be rated as ten goals in the female handicap system, said would like to see the royal husbands looking on while their wives play the game.

"I hope to see a young Royal female in the future playing the polo match and her husband watching from the sideline,” she told The Telegraph.

“My husband does it for me and I think it is completely possible and is probably going to happen."
