As a completely random aside, this was the set used by the BBC for the election in 1987. I think it was in N2, as that was slightly larger than N1 once they'd knocked through into the store room which had a lower ceiling.

I remember they also used this set every day for the Nine o' Clock News during the run-up to the election, with David Dimbleby co-hosting, and with special titles (although retaining the 'flying fish finger' music of the time)...

Were there any other years when they did this?

(Incidentally, I'm quite impressed on that video that the computer generated clock on the titles on (what's now) the Elizabeth Tower has the correct time, reflecting the slightly later than usual start time).
