As Feedback turns 40 this month, Roger Bolton quizzes outgoing Radio 4's Controller Gwyneth Williams about the twists and turns of her tenure before she passes her baton on to the new boss.

While BBC Sounds has come under criticism from some users, there has been high praise for one of its original podcasts. NB is a series about being non-binary - people who don't identify with traditional gender labels - and has struck a chord with many of its listeners. We hear their views on the series.

With Brexit dominating the news agenda, a number of Feedback listeners say that the issue of climate change is being underplayed. Roger talks to David Shukman, the Science Editor for BBC News, and Deborah Cohen, the Science Editor for BBC Radio, about coverage of the issue - and its prominence.
