If nothing else (2,5)
I believe the answer is:
at least
<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">if nothing else</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 at least that I've seen before include "Anyway" , "'If nothing else (2,5)'" , "Eat salt (anag) - if nothing else" , "No less than" , "As a minimum" .)
