I cite bold guys in corrupt financial institution (8,7)
I believe the answer is:
building society
'financial institution' is the definition.
(building society is a kind of financial institution)
'i cite bold guys in corrupt' is the wordplay.
'corrupt' indicates an anagram (a corrupted form).
'i'+'cite'+'bold'+'guys'+'in'='iciteboldguysin'
'iciteboldguysin' is an anagram of 'BUILDING SOCIETY'.
(Other definitions for building society that I've seen before include "it's not a bank" , "Financial institution" , "financial organisation" .)
