Capital of British Columbia (8)
I believe the answer is:
victoria
'capital of british columbia' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for victoria that I've seen before include "Queen - lake -sponge" , "London Underground line represented in light blue" , "Queen, Australian state and plum" , "Monarch" , "London rail terminus" .)
