The World at One now has 15 extra minutes to fill, following the shake-up of the afternoon schedule on Radio 4. Some listeners are delighted - others less so. Roger asks Nick Sutton, the programme's editor, what he plans to do with the time and how much investigation he has done into what the audience really wants to hear. Feedback itself will be staying the same length, but the Friday edition moves to 4:30 in the afternoon. The BBC Trust has launched a review into the impartiality of the BBC's reporting of the Arab Spring. Alison Hastings, chair of the Trust's Editorial Standards Committee, explains the reasons for the review and the scope of its inquiry. And a keen-eared listener who is also a ferret fan questions the identity of Eddie Grundy's ferret, Daphne. Judging by the sounds she makes, he accuses her of being... a guinea pig. All will be revealed. Presenter: Roger Bolton Producer: Karen Pirie A Whistledown production for BBC Radio 4.
