Former President of Yugoslavia (4)
I believe the answer is:
tito
'former president of yugoslavia' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for tito that I've seen before include "Head of state" , "Marshall ..., President of Yugoslavia from 1953" , "Yugoslavian freedom fighter and president" , "Revolutionary" , "Yugoslav marshal" .)
