English court framed by corrupt prison officer (9)
I believe the answer is:
inspector
'officer' is the definition.
(inspector is a kind of officer)
'english court framed by corrupt prison' is the wordplay.
'english' becomes 'e' (abbreviation).
'court' becomes 'ct'.
'framed by' means one lot of letters goes inside another.
'corrupt' indicates an anagram.
'e'+'ct'='ect'
'prison' with letters rearranged gives 'inspor'.
'ect' going into 'inspor' is 'INSPECTOR'.
(Other definitions for inspector that I've seen before include "auditor" , "Examining official" , "bluebottle!" , "Person whose job it is to examine efficiency as in schools" , "Police officer" .)
