This article examines the management of participation in calls to radio phone-in programmes. In the broadcast media, there are increasing occasions for interaction between `professionals' and lay members of the public, particularly within what have come to be known generically as public participation programmes. People call in to phone-in programmes for various reasons; to give opinions, to get advice, and often to ask questions. In the particular phone-ins analysed here, callers are invited to put questions to leading politicians of the (...) day about their election policies. In many institutional contexts for talk the role of questioner has been found to be a more powerful interactional position than the role of answerer. Through an analysis of the organization of the phone-in calls, this article argues that the potentially powerful discourse role of questioner is interactionally `defused' through the participatory framework of the call. The author shows how the mediated interactional structure of these calls limits the range of possible actions available to callers in their institutional position as questioners, and thus produces constraints on what callers can actually achieve in this particular context for institutional talk.

Public participation broadcasting has recently become the focus of attention in media studies, as well as from the social interactional perspectives of discourse and conversation analysis, and it has been argued in particular that the talk show genre has given new and enhanced status to the `authentic' voice of lay members of the public. What remains largely unexplored is how lay participants discursively construct authentic positions for their own knowledgeable participation in such discourse. Expert speakers in public participation broadcasts are (...) typically attributed names, rank, institutional affiliation and status, which legitimizes their position, and in so doing provides their warrant to talk about whatever issue they have been brought in to discuss. Lay participants typically do not have this status attributed to them, but need to establish their own position from which to talk. In this article I examine the public identities that lay speakers build for themselves in these broadcasts, and show how they routinely draw on a range of discursive resources to construct situated, local identities which provide a warrant for what they have to say.
