Next week sees the last ever episode of Radio 4's long running investigative series Face the Facts. Radio 4 says it's part of an ongoing effort to cut costs. Presenter John Waite recounts his most memorable moments during his 30 years on the frontline of investigative journalism.

The Green Party was hoping to launch their election campaign in a blaze of positive publicity earlier this week. But after leader Natalie Bennett experienced what she called an "excruciating mind blank" in an interview, the story took a very different direction. The BBC ran the story throughout the day - but was this too much coverage of Bennett's 'brain fade' at the expense of serious analysis of party policy? Katy Searle, the Editor of Political Newsgathering for BBC News, explains why the story deserved its airtime and place on the news agenda.

And while the rest of the BBC is giving up on broadcasting children's radio, BBC Radio Cymru has launched Tic Toc, a new programme aimed at a younger audience. Can Radio Cymru find success where others have failed? Head of Radio Cymru, Betsan Powys, explains what makes her venture different.
