Zarniwoop Vann Harl - Lady Cynthia Fitzmelton

Lady Cynthia Fitzmelton is described in the original radio script as "a sort of Margaret Thatcher, Penelope Keith character." She is responsible for christening the "very splendid and worthwhile yellow bulldozer" which knocks down Arthur Dent's house in "cruddy Cottington", and it gives her "great pleasure" to make a "very splendid and worthwhile" speech immediately beforehand.

She only appears in fit the first of the radio series, where she was voiced by Jo Kendall. Her "very splendid and worthwhile" lines were entirely dropped from later versions.
