Would make sense. Somehow I can't imagine the likes of Anna Ford or Nicholas Witchell presenting the summaries.
Pretty certain Anna Ford presented the morning daytime summaries in the early 00s when she was the main presenter of The One O'Clock News ?(with Darren Jordon sharing the duties)
Similarly I think Huw or Fiona (or Sian if she was sitting in) presented the afternoon summaries before presenting The Six O'Clock News?
This was after the 'virtual blue' sets and titles had been replaced by the first generation of Lambie Nairn Ivory and Red titles with David Lowe music.
You're absolutely correct, noggin. That change happened in May 1999 as I recall. Once the rebrand happened, the One presenter did the two late morning summaries and the Six presenter did the mid-afternoon summary. Before May 1999, the Six co-presenter did all the summaries as I mentioned earlier. The change probably happened because the Six co-presenter was jettisoned as part of the revamp.
On the day in question, as Jennie Bond was the Six co-presenter (despite Genome stating Moira Stuart) she would have been doing the daytime summaries. The newsflash was probably treated as another daytime bulletin for all intents and purposes.
