Disenfranchise seven, working around city (7)
I believe the answer is:
enslave
'disenfranchise' is the definition.
(thesaurus)
'seven working around city' is the wordplay.
'working' indicates an anagram.
'around' indicates putting letters inside.
'city' becomes 'LA' (Los Angeles).
'seven' with letters rearranged gives 'ensve'.
'ensve' going around 'la' is 'ENSLAVE'.
(Other definitions for enslave that I've seen before include "Take the liberty of" , "Deprive (someone) of liberty" , "Bind" , "Force into servitude" , "Put into bondage" .)
