<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">official pardon</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 amnesty that I've seen before include "Period of forgiveness for infractions" , "Men stay (anag.)" , "Dispensation" , "International organisation concerned with human rights" , "A general pardon as for rebels (7)" .)
