Re. central lobby. I think the issue is you have to have media accreditation passes to be situated there and I believe its only senior political correspondents at the BBC who have access, so the likes of Huw, Simon etc don't. College Green is different, as the temporary enclosure there is staffed by G4S and they will let journalists/members of the media through providing they have sufficient press ID. ?
Well, Jon Snow is stood in the lobby presenting C4 News right now
