Brown getting no say after uprising in prison (7)
I believe the answer is:
dungeon
'prison' is the definition.
(thesaurus)
'brown getting no say after uprising' is the wordplay.
'brown' becomes 'dun' (dun is a kind of brown**).
'getting' is a charade indicator (letters next to each other).
'say' becomes 'eg'.
'after uprising' says the letters should be written backwards.
'no'+'eg'='noeg'
'noeg' in reverse letter order is 'geon'.
'dun'+'geon'='DUNGEON'
'in' is the link.
(Other definitions for dungeon that I've seen before include "prison the result" , "Keep" , "Dark underground cell for prisoners" , "Eg, the Black Hole of Calcutta" , "Uncongenial accommodation" .)
