Photographs taken behind the scenes at the royal wedding of Prince Charles and Diana are to be auctioned.
The set of 12 photographs were taken at the wedding reception in Buckingham Palace on 29 July 1981, which followed the ceremony at St Paul's Cathedral.
Six of the images show the princess with members of her family and the wedding party, including the Queen.
The photos come from the collection of an assistant to the English photographer Patrick Lichfield.
Lord Lichfield, the Queen's first cousin once removed, was the only photographer allowed to take informal images of the royal family and their guests when they returned to Buckingham Palace.
