Policy advisor's banker ruins core review (9,6)

I believe the answer is:

insurance broker

'policy advisor's' is the definition.
(someone advising on an insurance policy)

'banker ruins core review' is the wordplay.
'review' is an anagram indicator.
'banker'+'ruins'+'core'='bankerruinscore'
'bankerruinscore' anagrammed gives 'INSURANCE BROKER'.
