I believe the answer is:
envoy
<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">diplomatic agent</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 envoy that I've seen before include "Emissary" , "Diplomatic messenger" , "Ambassador" , "Plenipotentiary" , "Diplomat" .)
