Doctored alumni pic belonging to the council (9)
I believe the answer is:
municipal
'belonging to the council' is the definition.
'doctored alumni pic' is the wordplay.
'doctored' is an anagram indicator.
'alumni'+'pic'='alumnipic'
'alumnipic' anagrammed gives 'MUNICIPAL'.
(Other definitions for municipal that I've seen before include "Relating to a town or district" , "Borough" , "Run by the council" , "of one's town" , "Relating to a town/district with local government" .)
