Kate Middleton appeared alongside several members of the Royal Family to attend the wedding of Harry Aubrey-Fletcher and Louise Stourton in Aldborough, North Yorkshire.

Miss Middleton, wearing a black velvet coat, black dress and black pill box hat, walked alongside Prince Harry and Princess Beatrice as they left the service.

Prince William was an usher at the event and as he left, he made a joke to the waiting crowds that it was "not my wedding yet!"
