That all seems very odd. It was a requirement of the IBA circuit routing that no ITV company would be more than one circuit switch ‘away’ from a source of ITN precisely for the purposes of news flashes etc. I wonder if this was very late at night and the duty newscaster at ITN had already left the premises and there was no-one there to actually present a newsflash? A rip and read locally perhaps? 

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
