<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">decide not to attend</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 skip that I've seen before include "Ignore" , "Jump; builder's container" , "Rubbish container - miss - jump" , "Container used to collect and dump waste" , "Pass over, omit" .)
