Finally closing in on a full grid, although it sounds like that's really only the start of this puzzle...
Could do with some nudging on any of:
5ac. Council nervous having book for Conservative member empty of pride (7)
14ac. Each tree trunk introduces gum sources (5)
8d. Poor plaintiff raising universal legal right (4)
9d. AI totally accepts sound of Soay accent (9)
If that's too many to ask about, apologies and no worries, I'll take any of them!
