I believe the answer is:
castro
<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">cuban leader</span>' is the definition.<br/ ><span class="explanation-format__explanation">(I've seen this before)</span><br/ ><br/ >This is all the clue.<br/ ></span>
(Other definitions for castro that I've seen before include "Man of Cuba" , "Cuban co-star" , "Actors in Cuba" , "Cuban leader, d. 2016" , "Fidel . . . . . .,retired Cuban leader" .)
