<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">royal staff</span>' is the definition.<br/ ><span class="explanation-format__explanation">(I've seen this before)</span><br/ ><br/ >This is all the clue.<br/ ></span>
(Other definitions for sceptre that I've seen before include "Royal staff (paired with 2 down)" , "Respect (anag) -- symbol of ruler's authority" , "Monarch's ceremonial staff" , "Emblem of royalty" , "Queen's staff" .)
