Letter: Sonia Rolt obituary

In addition to her work as a conservationist, for many years Sonia Rolt played an active part in the organisation of the Cheltenham literature festival, notably in the early 1960s, when its future was far from assured. In the late 80s and early 90s, Sonia’s lively and cheerful presence was a memorable feature of meetings. And as programme director in 1991 I was grateful for her unwavering encouragement and support.
