Last Christmas's panto at the Prince of Wales's Institute starred former director Richard John doing his impression of Prince Charles - without changing into costume. A pantomime of a different sort took place last week when the death knell was officially sounded for Perspectives magazine. This was not unexpected for editor Giles Worsley, former Country Life architecture correspondent, Royal Fine Art Commissioner, deputy director of the institute and cousin of the Duchess of Kent. What hurt, however, was another decision by the institute's council - to scrap its think tank, which Giles headed. He has now written to friends announcing his resignation from his institute post. Whether this is more in sorrow than anger is hard to say. If he wants to know what it feels like to be discarded, he can always ask Richard John.
