Assume control and receive deliveries? (4,4)
I believe the answer is:
take over
'assume control' is the definition.
(I've seen this before)
'receive deliveries?' is the wordplay.
'receive' becomes 'take' (taking is a kind of receiving).
'deliveries?' becomes 'over' (I've seen this before).
'take'+'over'='TAKE-OVER'
'and' is the link.
(Other definitions for take over that I've seen before include "This bid is for control of a business" , "Act of assuming control" , "Assume control of" , "Company buyout" , "Buying out of one company by another" .)
