Look's like BBC World News / BBC Four are doing their own thing a 7pm with World News Today
Either that or BBC4 Haven't correct their listing properly!
I was looking at both schedules World News Today is listed on both channels at 19:00GMT and World switches at 20:00GMT to BBC News Channel. BBC4 always takes world output at 7pm, as Beyond 100 Days is shown with WN graphics
Looks like the listings got changed at the last moment as BBC4 Are indeed taking the first half hour of the News Special.
Not sure of the exact name of those studios overlooking the city, but Christian has just made specific reference to his backdrop tonight being a real view of the Thames and London, rather than the fake view normally behind him in the basement of World News HQ.
And one of the laptops appears to have been removed.
Looks like tonight's BBC News at Ten will be coming out from studio B given the fact they are rehearsing in studio B's gallery... That explains why studio B is not used by WN today and the Five comes out from studio A...
