<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">position of control</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 helm that I've seen before include "Steer (a boat/ship)" , "part of boat near stern" , "Steering device" , "Wheel that controls ship's rudder" , "Tiller - part of armour" .)
