anon
<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">in due course</span>' is the definition.<br/ ><span class="explanation-format__explanation">(I've seen this before)</span><br/ ><br/ >This is the entire clue.<br/ ></span>
(Other definitions for anon that I've seen before include "Of unknown name (abbr)" , "Nameless - presently" , "Having no known name" , "Soon, precious stone" , "devoid of credit" .)
