Star organised rebel city (9)
I believe the answer is:
celebrity
'star' is the definition.
(thesaurus)
'organised rebel city' is the wordplay.
'organised' indicates anagramming the letters.
'rebel'+'city'='rebelcity'
'rebelcity' is an anagram of 'CELEBRITY'.
(Other definitions for celebrity that I've seen before include "target of paparazzo?" , "Famous person seen in rebel city" , "name" , "Well-known or famous person" , "Star" .)
