Political crime (5)
I believe the answer is:
graft
'political crime' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for graft that I've seen before include "Hard work - illicit gain" , "Hard work; bribery" , "Hard work - corrupt profit" , "Make parts of different plants grow together" , "Means of propagation - hard work?" .)
