<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">public declaration of policy</span>' is the definition.<br/ ><span class="explanation-format__explanation">(I've seen this before)</span><br/ ><br/ >This is the entire clue.<br/ ></span>
(Other definitions for manifesto that I've seen before include "See 6" , "Declaration of intentions by a political party" , "Soften aim (anag) - platform" , "Pre-election promises" , "party programme" .)
