<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">not challenged</span>' is the definition.<br/ ><span class="explanation-format__explanation">(I've seen this before)</span><br/ ><br/ >This is the entire clue.<br/ ></span>
(Other definitions for unopposed that I've seen before include "Not challenged" , "Elected . . . . . . . . .; no other candidate" , "Assembly" , "without query" , "so carried?" .)
