I believe the answer is:

<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">magnate</span>' is the definition.<br/ ><span class="explanation-format__explanation">(I know that magnate can be written as mogul)</span><br/ ><br/ >This is all the clue.<br/ ></span>
(Other definitions for mogul that I've seen before include "Mr Big?" , "Powerful person, potentate" , "bigwig" , "Big cheese - mound of hard snow on a ski slope" , "Powerful businessperson" .)
