Claire was so well regarded that the Prince of Wales asked her to teach his sons how to play polo at the Beaufort Polo Club. William and Harry have continued to be avid polo players and have competed against one another in charity matches.
Last August, Harry travelled to Aspen, Colorado to compete in the Sentebale ISPS Handa Polo Cup to raise funds for his charity, Sentebale. Meanwhile, Prince William also took part in a match in Windsor last summer.

Claire was the first woman in the world to reach five goals in 1986, as well as the first to win the County Cup in 1972 and the Queen's Cup in 1979. She still holds the women's high-goal handicap record today.
Her children are all polo players and compete internationally. The Duke and Duchess of Cambridge and Prince Harry attended Mark Tomlinson's wedding to Laura Bechtolsheimer in the Swiss resort of Arosa in 2013.
