Prince Charles is to star in a fly-on-the-wall documentary to mark his 60th birthday.
The Duke of Edinburgh has already started filming the BBC television programme, which is likely to air sometime in November.
A source told The Daily Telegraph: “It is a serious, heavyweight programme about his working role. They have been pointing a camera at everything he does rather than having long chats about his life and his family late at night on the sofa.”
The BBC confirmed: “We are filming a long-term project with His Royal Highness the Prince of Wales to mark his 60th birthday.”
Last year, the television corporation came under fire after it released footage which falsely suggested the queen stormed out of a photoshoot with photographer Annie Leibovitz following a row over whether the monarch should remove her crown.
The BBC’s strained relationship with the royal family was also apparent in 2005, when Prince Charles was overheard talking about the corporation’s royal reported Nicholas Witchell to his sons, Prince William and Prince Harry.
Charles said: “These b****y people. I can’t bear that man. I mean, he’s so awful, he really is.”
