Last offer (4,3)
I believe the answer is:
hold out
I believe this clue is a double definition.
'last' is the first definition.
(I know that last can be written as hold out)
'offer' is the second definition.
(I've seen this before)
(Other definitions for hold out that I've seen before include "Offer as inducement or resist capture" , "Offer inducement or maintain resistance" , "Resist (against siege)" , "Continue to be sufficient" , "Offer - last" .)
