The Princess of Wales was seen smiling and joking with other royals during the Order of the Garter service a year after missing the event while receiving cancer treatment.
Catherine appeared to be in good spirits as the sun shone and she watched the procession of Ladies and Knights of the Garter through the grounds of Windsor Castle to St George’s Chapel.
The princess was joined by the Duchess of Edinburgh and Vice Admiral Sir Tim Laurence at the chapel’s Galilee porch, a traditional vantage point to see the spectacle.
The King and Queen followed convention and were at the back of the procession dressed in white plumed hats and dark blue velvet robes, as were the other members of the order.
