Kate Middleton joined by Prince Edward and Sophie at Buckingham Palace garden party

The Duchess of Cambridge enjoyed a wonderful afternoon out with the Earl and Countess of Wessex as the trio attended a garden party at Buckingham Palace alongside Princess Alexandra on Wednesday. This was the second garden party of the year held at the Queen's London residence, although sadly Her Majesty was not in attendance and does not plan to be for similar events this spring due to her mobility issues. READ: The Queen presented with unbelievable gift at home Kate, Edward and Sophie were in high spirits as they put on their finest daywear and mingled with the hundreds of members of the public who were invited to the special event. While the Earl looked smart in a top hat and tails, the Duchess and the Countess were typically stylish in summer dresses and matching hats. See the best photos from the day…
