I believe the answer is:

<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">capital of saskatchewan</span>' is the definition.<br/ ><span class="explanation-format__explanation">(I've seen this in another clue)</span><br/ ><br/ >This is all the clue.<br/ ></span>
(Other definitions for regina that I've seen before include "ER, Elizabeth ..." , "Queen (Latin)" , "in Canada" , "Queen in legal issues" , "Reigning queen's title" .)
