I fail to see how there still won't be a 5pm UK news hour though?
I can't see any circumstance where Focus on Africa will go out on the UK stream at 5:30pm, and it's hardly appropriate to have a back half hour filler program on at 5:30pm for UK viewers.

So why can't the current arrangement of the 1pm news presenter and gallery team also doing the 5pm hour on the UK stream continue?

Focus on Africa won't go out in the UK (unless, perhaps, there was a really big Africa story), but during the Ukraine crisis they showed that they could have World presenters continue in the UK (and I think some World regions) while Focus on Africa went on as normal elsewhere. I suspect you'll have that set-up on the new channel, particulary with Focus coming from Nairobi.

It'd be good to get some UK-only content at some point of the day, but it appears that (at least for now) that isn't the path they're going down. A visualised PM programme has been suggested in the past for the 17:00 hour, but I think the issue with a News at Five hour is more the gallery teams and studio space rather than presenters.

I just find it difficult to believe that it's not possible to utilise the 1pm team for another hour of UK only news at 5pm, as is being done now (although I obviously don't know if the 1pm gallery team do the 5pm hour currently).
Wasn't the idea of bringing in Huw to do the 5pm hour in 2006, because News 24 saw this as one of their "prime" viewing hours? 

Even once the musical studios of the next few months is over, assuming the new BBC (World) News Channel is in E and Network/London in B, with C and A mothballed, won't studio D still be available for a 5pm UK only news hour with the 1 team?
The priorities for the UK stream of the new channel seem very wrong if a 5pm UK only news hour is not possible (or management don't want it), yet management want 2 hours of Nicky Campbell in the morning to count as prominent "UK only" content on the channel
