This is quite old news - but still no scheduling details.
C4 have said it will feature more in-depth analysis of the main stories than C4 News (I though that was the point of C4 News).
While I think there is space in the market for an afternoon news bulletin (say at 4pm), I think this may be like a "C4 News Extra" type programme airing at 8pm after the main bulletin.
One thing that does concern me about this is that C4N itself could be diminshed. Could C4N be reduced in the long term to 30 minutes and viewers then be persuaded to switch over to M4 for 'more detail'?
C4N is excellent and I sincerley hope that it doesn't suffer.
