The legal capital of Bolivia (5)
I believe the answer is:
sucre
'the legal capital of bolivia' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for sucre that I've seen before include "Bolivian city" , "City of Bolivia" , "Bolivia's constitutional capital" , "sweetener abroad" , "Legal capital and former monetary unit of Bolivia" .)
