Sarah Snow (later Parry) (Lucy Aston) – Diana's niece, who runs a successful modelling agency in London. Diana usually feigns indifference to Sarah, but it is obvious that deep down she cares very much for her. Sarah marries the crooked businessman Sam Parry (Christopher Bowen) during Series 2: the marriage does not last long, but it does result in Sarah having a child. The baby girl is the apple of Diana's eye and is named 'Diana' after her great-aunt. Sarah calls Diana "Aunty". Diana hates the term and constantly says, "Don't call me 'Aunty'."
