I don’t think the bbc bosses are too fussed with Uk audiences declining, they’ve already accepted that and the results are what we are watching now, what they will care about is if world audiences are declining and therefore affecting their advertising revenue(maybe that’s why we have these half baked programme strands) as I imagine this merged operation is now reliant on commercial money.

If this were true, why would they have so substantially increased the proportion of UK stories featured on the channel (compared to World), frequently giving them prominence over arguably more newsworthy international stories. 

Going by the figures I've seen quoted and in BBC Global News financial reports, I'd estimate it's about 40:60 licence:commercial money.
