Oops, a little late in bringing it up, but there's a NO2ID-organised fringe meeting this evening in Brighton, in amongst all the others.
Address is Brighthelm Auditorium, North Road. 7.30-8pm. Speakers aren't listed on the above link, but the Rt Hon Clare Short's on the panel, for sure. Have't got a leaflet one me now, so can't tell you who the others are. Rumours are that Home Office ID Honcho Andy Burnham will be turning up as well, so could be a good one.
