The editor of The World at One answers listeners' complaints about his programme's interview with the actor Nigel Havers, there's Radio 4's new comedy series about cancer survivors, and the dos and don'ts of eating on the radio.

Feedback received many emails this week from listeners who question The World at One's decision to interview actor Nigel Havers about the integrity of his aunt Baroness Butler Sloss and her appointment to lead a government inquiry into child sex abuse. Was it a case of celebrity leakage? The programme's editor Nick Sutton answers his critics.

Also, should we be laughing at cancer? Some listeners are turned off by the new radio comedy Bad Salsa which looks at dancing and cancer survivors. Roger discusses the thinking behind the programme with the writer Kay Stonham and producer Alison Vernon-Smith.

And we consider the art and perils of eating on the radio with Woman's Hour presenter Dame Jenni Murray and the broadcaster Simon Parkes.
