Ugandan tyrant
I believe the answer is:
amin
'ugandan tyrant' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for amin that I've seen before include "Idi . . . . Once ruled Uganda tyrannically" , "Brutal dictator" , "'Last King of Scotland'" , "Ugandan dictator" , "Former African despot" .)
