<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">sadat'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 nasser that I've seen before include "Former President of Egypt" , "Former Egypt leader" , "UAR president" , "-- Hussain, ex-cricketer" , "old Egyptian leader" .)
