Earlier, Philip donned the red tunic and heavy bearskin hat of his rank of Colonel in the Grenadier Guards at the annual birthday parade for the Queen – also known as Trooping the Colour.
Philip has been recovering at home since leaving the hospital, where he was treated for a bladder infection. But on Saturday, he was seen standing ramrod straight as 1,600 soldiers paraded in front of the Queen, 86. He and the Queen (in a bright yellow coat and dress outfit by her in-house designer Angela Kelly) were transported from the palace to the parade grounds in a glass coach for the military spectacle.
Kate, in a dove gray dress by Erdem with a hat by Jane Corbett, delighted the crowds along the Mall by riding in an open-topped carriage with Prince Harry and the Duchess of Cornwall to the official birthday parade.
William arrived for the ceremony on horseback in his role – and full uniform of Colonel of the Irish Guards.
Elsewhere, Princesses Beatrice and Eugenie rode in a carriage with their father, Prince Andrew.
Kate’s wedding dress designer, Sarah Burton, received an OBE (Order of the British Empire) in the Queen’s birthday honors. Also honored: Kate Winslet and Kenneth Branagh, who was knighted. Gary Barlow, who organized the jubilee concert, was given an OBE as well.
