I can't imagine the mezzanine ever being used as a presentational position, as I don't think the LED screens in that upper area are particularly high resolution when close up (I know there is a technical term for that, but I don't know it off the top of my head).

Think it could be implemented at some level for election coverage. Don’t think interviews would work up there but maybe news updates, in terms of the screens I’m sure they could just bring something in a bit more detailed if they need to for the section they use.

I can just imagine it . . . "Now to BIG MOIRA clutching a handrail for a news update", on the 2 foot wide mezzanine struggling to read an autocue on a camera 6 feet below her.  

It was bad enough with the dodgy LED screens they used at Elstree for some of the last Election broadcasts. When close up they looked dreadful.
