A new stage production in which British royal Prince Charles' wife CAMILLA, DUCHESS OF CORNWALL has affairs with his father and son opened to controversy in London last night (20JUL06). A RIGHT ROYAL FARCE is set shortly after the fictional death of Queen Elizabeth II and sees Camilla portrayed as a nymphomaniac who sleeps with both her father-in-law Prince Philip and his grandson - her son-in-law - Prince Harry. The play is written by Spectator magazine theatre critics TOBY YOUNG and LLOYD EVANS and is being shown at the British capital's Islington Theatre. SIR ROBERT FELLOWES, the brother-in-law of the late DIANA, Princess Of Wales, says, "Members of the royal family have been the target of satirists for years. But this really does go too far and it does sound offensive."
