SIR – In my opinion there is only one possible replacement for David Dimbleby as chairman of Question Time (report, June 18) who has the status, experience and knowledge to deal with politicians and guests alike – and that is John Humphrys. J Martin Lewis

SIR – One thing’s for certain: if you’re white, male, and Anglo-saxon, then forget it. Steve Haynes
