I suppose the one thing massively in its favour as a BBC channel is that things can be put on iPlayer, so the content is more discoverable than if it was saved to an obscure parliamentary website.

Also, not often but occasionally, when the BBC NC has taken live parliamentary coverage in the past, it has broken away from it after a bit but been able to say “coverage continues on BBC Parliament”. They couldn’t really do that if they didn’t run the “shared” Parliamentary channel.

Being a BBC service also allows Parliament to piggyback on BBC Millbank staff who work for News - including programmes like Politics Live. So I imagine that this means people covering technical roles, etc, also have dual functions which means (practically speaking) being an integrated BBC service keeps cost down even further.
