LONDON -- The Princess of Wales has joined other members of the royal family on a Buckingham Palace balcony at the end of the King's Birthday Parade.
"I am making good progress, but as anyone going through chemotherapy will know, there are good days and bad days," Kate said in a statement, adding that she faces "a few more months" of treatment. Kate was likely to join other members of the family on a Buckingham Palace balcony to watch a flypast of military aircraft -- and delight the crowds below. The princess has not made any public appearances since December.
Prince William, in military dress uniform, rode on horseback for the ceremony, in which troops in ceremonial finery parade past the king with their regimental flag, or "color." The display of precision marching and martial music stems from the days when a regiment's flag was an essential rallying point in the fog of battle.
Charles, 75, disclosed his cancer in February, and has recently eased back into public duties. He attended commemorations last week for the 80th anniversary of D-Day, the Allied invasion of Nazi-occupied Europe on June 6, 1944.
