William and Kate share a mutual love of sport and it came as no surprise to see the Duchess getting stuck in to a game of volleyball on Friday when she made her first official solo appearance since giving birth to Prince George.
Prince William's wife cultivated a love of hockey during her years at Marlborough College, and before that, at St Andrew's School in Pangbourne where she also played tennis, swimming, netball and rounders.
