Butcher's trying to get minister to... (4,5)
I believe the answer is:
look after
'minister to' is the definition.
(thesaurus)
'butcher's trying to get' is the wordplay.
'butcher's' becomes 'look' (I've seen this in other clues).
'trying to get' becomes 'after' (someone 'after' something is trying to get it).
'look'+'after'='LOOK AFTER'
(Other definitions for look after that I've seen before include "Watch over" , "Take care of" , "mind" , "Peer trying to find" , "Tend" .)
