Yield for Mussolini? (7)
I believe the answer is:
produce
'yield' is the definition.
(I've seen this before)
'for mussolini?' is the wordplay.
'for' becomes 'pro' (I've seen this before).
'mussolini?' becomes 'duce' (I've seen this before).
'pro'+'duce'='PRODUCE'
(Other definitions for produce that I've seen before include "Make, manufacture" , "Fresh fruit and veg for market - crop due (anag)" , "Bring forth or yield" , "Bear" , "Make, create" .)
