Brother Livingstone is finished (6)

I believe the answer is:

broken

'is finished' is the definition.
(thesaurus)

'brother livingstone' is the wordplay.
'brother' becomes 'bro'.
'livingstone' becomes 'ken' (Ken Livingstone is a famous UK politician).
'bro'+'ken'='BROKEN'

(Other definitions for broken that I've seen before include "Shattered, perhaps emotionally" , "Made inoperative" , "out of order" , "no longer working?" , "Smashed or tamed" .)

I've seen this clue in The Independent.
