I believe the answer is:
agents
<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">brokers</span>' is the definition.<br/ ><span class="explanation-format__explanation">('agent' can be a synonym of 'broker')</span><br/ ><br/ >This is the entire clue.<br/ ></span>
(Other definitions for agents that I've seen before include "They act for actors" , "Factors" , "Sales reps" , "Spies" , "They do business on behalf of others" .)
