Settle dodgy scene involving politician (8)
I believe the answer is:
ensconce
'settle' is the definition.
(synonyms)
'dodgy scene involving politician' is the wordplay.
'dodgy' indicates anagramming the letters (a dodgy or wrong order of the letters).
'involving' is an insertion indicator.
'politician' becomes 'con'.
'scene' with letters rearranged gives 'ensce'.
'ensce' placed around 'con' is 'ENSCONCE'.
(Other definitions for ensconce that I've seen before include "Settle comfortably, establish" , "Fix firmly" , "Firmly establish" , "Establish (oneself in a comfortable safe place)" , "Settle firmly" .)
