<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">tallied</span>' is the definition.<br/ ><span class="explanation-format__explanation">(agreeing is a kind of tallying)</span><br/ ><br/ >This is all the clue.<br/ ></span>
(Other definitions for agreed that I've seen before include "Consented and concurred" , "Gave consent" , "Harmonised" , "'Concurred, assented (6)'" , "It's a deal!" .)
