Ballots for Blair Seats
Tony Blair's appearance before the Iraq Inquiry is public but has generated such interest that seats will have to be balloted. Sir John Chilcot, chairing the inquiry, says "We believe the fairest way to do this is to allocate seats by ballot. Note that, actually, certain places are reserved for priority groups (e.g. relatives of servicemen), but those places will also be subject to a ballot among members of the priority group.
On the subject of random selection, Michael Cholbi is contemplating the merits of random selection to assign student groups over at ISW.
