The announcement is the first to be announced for the princess since she stepped back from official duties to convalesce following abdominal surgery on January 16.
Buckingham Palace sources said that planning for the King’s future engagements continued, with allowance to be made for his changed circumstances, if necessary, nearer the time.
The Army’s website, which is selling tickets for £15 ($31.30), said the Trooping the Colour attended by the princess would be the same as the parade traditionally inspected by the monarch.
The site said: “Trooping the Colour reviewed by Her Royal Highness The Princess of Wales is identical to Trooping the Colour reviewed by His Majesty The King, with the exception that some additional mounted officers ride when His Majesty The King is present.
“Taking part will be over 1400 soldiers of the Household Division and The King’s Troop Royal Horse Artillery, including 400 musicians from the Massed Bands, all of whom will parade on Horse Guards for the second of two formal reviews.
“Trooping the Colour reviewed by Her Royal Highness The Princess of Wales also includes 250 soldiers from the Foot Guards who will line the processional route along The Mall. The soldiers will be inspected by Her Royal Highness The Princess of Wales, Colonel Irish Guards.”
