earlier also had a tory member, an activist in it, and so, we do try and get a range and get a real sense of the place and obviously try and avoid any sense of stereotyping. i'm interested in — and i think a lot of viewers are interested in — whether the bbc really monitors who gets used in vox pops and what it reveals. yes, we do monitor and evaluate and assess where we go to, and we do that over time and who we're talking to. and there's a particular thing, i guess, with television news bulletins where you're trying to encapsulate a range of public opinion and insight, which is adding to understanding of the story, perhaps in 2.5 or 3 minutes, as opposed to, say, question time, where you can get insights and an audience feedback, say, over an hour or the nicky campbell phone—in on 5 live and that sort of format. so, there are particular challenges around television news bulletins, but in people like alex forsyth and ed thomas, we have really experienced, expert correspondents who are able to deliver that for us. thank you.
