<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">insurance brokers</span>' is the definition.<br/ ><span class="explanation-format__explanation">(I've seen this in another clue)</span><br/ ><br/ >This is the entire clue.<br/ ></span>
(Other definitions for agents that I've seen before include "travelling salesmen" , "They operate on behalf of others" , "Sales reps" , "They act for actors" , "Instruments" .)
