New prison to include European court examiner (9)
I believe the answer is:
inspector
'examiner' is the definition.
(I know that examiner can be written as inspector)
'new prison to include european court' is the wordplay.
'new' indicates anagramming the letters.
'to include' is an insertion indicator.
'european' becomes 'E' (abbreviation e.g. EU).
'court' becomes 'ct' (abbreviation used in road names).
'prison' anagrammed gives 'inspor'.
'e'+'ct'='ect'
'inspor' placed around 'ect' is 'INSPECTOR'.
(Other definitions for inspector that I've seen before include "reviewer" , "leading rank" , "Examining official" , "one to check" , "bluebottle!" .)
