Raise home counties sheep (3,2)
I believe the answer is:
set up
'raise' is the definition.
('set up' can be a synonym of 'raise')
'home counties sheep' is the wordplay.
'home counties' becomes 'se'.
'sheep' becomes 'tup' (tup is a kind of sheep).
'se'+'tup'='SET-UP'
(Other definitions for set up that I've seen before include "The way something is arranged" , "Established" , "Arrangement; trick" , "Conspiracy" , "Contrived situation" .)
