There are plenty of examples of it being a rip and read, even the C4 Continuity Announcer has a go here

And this is clearly the LWT continuity studio on Central, but I'm not clear whether that is LWT's announcer or somebody from ITN who has made the trip to the South Bank

I’m afraid I know nothing of C4/ITN arrangements in those days. Appears to be very late at night/early morning and again I wonder if ITN’s studio/production staff were tucked up at home? 

As an aside you’ll note the ad break (the last of the evening) contained only Public service announcement type ‘stuff’. Where I worked the last C4 break was always scheduled with no ads to cover the possibility of an ad not being played out correctly earlier in the day for some reason or other - it could be re-inserted in the last break otherwise it would be filled with COI’s or somesuch etc as we see here. (Gosh, takes me back to my days in C4 local ITV presentation and programming up the ACR etc).

The second clip certainly appears to be LWT’s presentation studio - it’s an ITN journalist whose name I can’t remember it’s certainly not the continuity announcer. ITN was only a few minutes away in a cab.
