Liberator of Brazil from drugs in turn corrupt (10)
I believe the answer is:
nutcracker
'liberator of brazil' is the definition.
(as in a Brazil nut)
I can't explain the rest of the clue.
(Other definitions for nutcracker that I've seen before include "The --, ballet by Tchaikovsky" , "Brazil under pressure from this" , "piece of Pavlova" , "The work of Tchaikovsky" , "Bird of the crow family" .)
