The trundle cam can only be controlled by Studio E’s gallery, yes. So they could record a new, better-timed version of the trundle using E some time, then re-edit the rest of the opening to match better. Or, like you say, drop in the shorter template from another gallery and add the trundle cam. But that’s attention to detail which is sorely lacking at BBC News these days. Pretty much everything is left as-is. Even after literally years, the newsroom hoop hasn’t been repaired, for example.

Also, regarding the “number of days each presenter appears” details, don’t forgot that two presenters will be doing one bulletin in situations where there is an anchor on location (so that doubling up uses two “days”) and also, for full-time BBC staff, presumably sick days come out of the number of days too. So presenter x can be down to appear at Six next Tuesday, but they call in ill - you will need to get cover from someone else, obviously, but presenter x would still have “done one day” (presumably, as they would have been paid).

I say all that to point out that you do need more days available than the bare maths would allow!

Also, as far as I know, Reeta did also move across to the BBC One team officially, along with Ben and Jane - so they are three presenters up on before, even though all three did regularly appear before as well. Victoria seems to be regarded as a senior UK presenter, so appears on BBC One as relief alongside her work on Newsnight and podcasts.

All are perfectly capable of presenting any of the BBC One bulletins in my view, so no need for a fixed team. The idea that each bulletin is actually just “the news” is probably how the BBC like it, as it means that viewers can identify with the BBC News brand as a whole rather than particular output.
