Meanwhile, we might do it when 'e dies! (7)
I believe the answer is:
interim
'meanwhile' is the definition.
(I've seen this in another clue)
I cannot understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for interim that I've seen before include "Caretaker" , "Temporary - provisional" , "Meanwhile" , "Stopgap" , "Meantime - provisional" .)
