Former Yugoslav leader (4)
I believe the answer is:
tito
'former yugoslav leader' is the definition.
(I've seen this before)
This is all the clue.
(Other definitions for tito that I've seen before include "Yugoslav marshall, prime minister and president, d. 1980" , "Josip Broz, d. 1980" , "Statesman once" , "Josip Broz pseudonym" , "Head of state" .)
