I believe the answer is:
nuncio
<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">papal legate</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 nuncio that I've seen before include "Papal envoy" , "Papal diplomat" , "See man" , "Sent by the Pope" , "Pope's diplomatic representative" .)
