Sheltered by rogue state, a gentle property seller (6,5)
I believe the answer is:
estate agent
'property seller' is the definition.
(I've seen this before)
'sheltered by rogue state a gentle' is the wordplay.
'sheltered by' says the answer is hidden in the clue.
'ESTATE AGENT' is hidden in the letters of 'rogue state a gentle'.
(Other definitions for estate agent that I've seen before include "House seller" , "Man of property" , "Person supposed to facilitate house sales" , "Property dealer" , "person to manage property" .)
