Prince William (left) and Prince Harry
They are sometimes known as military brothers in arms, but next month Prince William
and Prince Harry
are due to come face-to-face in battle – during a polo game.
The royal siblings will take each other on at one of their favorite sports as they compete for the Sentebale Polo Cup on June 12 near Windsor.
And there will be a special face in the crowd to witness the duel – Catherine, Duchess of Cambridge
. Suntanned and fresh from her memorable honeymoon
in the Seychelles, Kate is set to be at the event.
The day before, Kate is scheduled to appear at her first official royal event, the Trooping the Colour ceremony that marks Queen Elizabeth's birthday.
At the polo game, Harry, 26, will play for a team representing his charity Sentebale
, which he established with friend Prince Seeiso of Lesotho to aid young people in the southern African kingdom. William, 28, will play for a team representing one of his patronages, Tusk Trust.
The Sentebale Polo Cup, which is sponsored by Royal Salute whisky, was to have taken place in Dubai in March, but was called off at the height of the turmoil caused by the Arab Spring uprisings in the region.
