Gwyneth Williams is in her fifth year as the controller of Radio 4 and has made her mark with various radical changes - including bringing a former Eastenders' producer to The Archers, cutting 12 minutes from You and Yours and bringing visualisation to a variety of Radio 4 programming.

For the final episode of this series, Feedback listeners speak directly to the Controller and give their views on the network. Loyal Archers Addicts ask how much free rein the editor should have when many listeners are unhappy with the programme's current direction.

Gwyneth is also asked whether there is a theme to the daily '12 o clock slot' that has divided listeners, and whether 15 minute programmes are long enough to over complex topics.

Radio 4's leap towards a dazzling digital future is also put under scrutiny as a listener asks whether radio programmes truly benefit from visual elements.

And how tight is her Radio 4 budget for programmes, given that even more cuts are coming soon?
