<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">mubarak's predecessor</span>' is the definition.<br/ ><span class="explanation-format__explanation">(I've seen this in another clue)</span><br/ ><br/ >This is all the clue.<br/ ></span>
(Other definitions for sadat that I've seen before include "assassinated president" , "Former president of Egypt" , "Former Egyptian president" , "World leader" , "Former leader" .)
