To launch the diamond jubilee weekend, BBC One is broadcasting a personal tribute to Her Majesty the Queen by His Royal Highness the Prince of Wales. Through previously-unseen photographs and cine films from Her Majesty's private collection - many of them shot by the Queen herself - the prince reflects on various public events and private family moments during the sixty years of the Queen's reign. In some cases, the prince himself has never seen the footage before. The prince is filmed in the private quarters of Windsor Castle and Balmoral, as well as at Buckingham Palace and Highgrove.
