My memory on this is a bit hazy now but wasn't N8 used between 21:30-22:00 to allow N6 to prep for the Ten? Of course they didn't have that problem at 17:30 as the Six came from TC7 which was free anyway.

Yeah, that was the reason. Ten needed to be able to rehearse and record studio-based segments for reports so one of the evening shift presenters had to run up to N8 (including doing the 21:30 BBC World News summary). The thing that has always confused me is why after Newsnight left for NBH did they not move the Ten to TC7 and stop with the weird studio shuffle - would've better utilised the TC7 studio team and meant they no longer had to fire up N8 for 30 minutes a day in the last few weeks.

Nearly 4 and half hours from News 24 in the early hours of November 20th 1997:

It's so good to be able to see full archive news programmes - I think it's really important to be able to see how the content and structure has structured over time as well as the presentation. Such a shame that there are so little full News 24 or World programmes archived anywhere public - and the little that survives of News 24 (or even the News channel) is overnight.
