Irishman I brought forward for a summary (2,3)
I believe the answer is:
in all
'for a summary' is the definition.
('in all' is used to introduce a summary)
I can't explain the remainder of the clue.
(Other definitions for in all that I've seen before include "Taking everything into account" , "Summarising" , "Everything considered" , "With everything counted" , "Taken as a whole" .)
