<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">britain's blair</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 tony that I've seen before include "Shortened man's name" , "award for work in theatre" , "Blair; having style (slang)" , "Weller senior's nomination" , "- - Adams, 7 legend" .)
