Carry on with a summary (6)
I believe the answer is:
resume
This clue is a double definition.
'carry on' is the first definition.
(I've seen this before)
'a summary' is the second definition.
(I know that resume is a type of sum-up)
'with' is the link.
(Other definitions for resume that I've seen before include "Continue after a break" , "Short descriptive summary" , "Start or take up again" , "list of achievements in Washington?" , "Re-open" .)
