Prince William & Kate: Sunday Church with Prince Harry!

Prince William and his wife Kate arrive at Windsor Castle to attend a church service on Sunday (June 12) in London, England.

The service marked the 90th birthday of the 28-year-old Duke of Cambridge’s grandfather, Prince Philip, Duke of Edinburgh.

That same day, William and his younger brother Prince Harry, who also attended the service, played in a charity polo match held at Coworth Polo Club.

William left with bragging rights as his team beat Harry‘s!

Earlier this weekend, William and Kate participated in the Trooping the Colour Parade honoring the Queen‘s birthday, which was in April.
