PEOPLE understands that Prince Harry flew to the U.K. to show his support for the case. He informed bothKing Charles, 74, andPrince William, 40, that he would be in the U.K. for the proceedings, but it’sunlikely that Harry will see his father or brotherduring the trip.

Prince William is not at his Windsor home while he and his wife,Kate Middleton, spend time with their three children during a school break. The Prince and Princess of Wales typically try to keep royal duties to a minimum whilePrince George, 9,Princess Charlotte, 7, andPrince Louis, 4, are off from school.
