Renegade can’t tour after review (8)
I believe the answer is:
turncoat
'renegade' is the definition.
('turncoat' can be a synonym of 'renegade')
'can't tour after review' is the wordplay.
'after' says to put letters next to each other.
'review' indicates an anagram.
'cant'+'tour'='canttour'
'canttour' with letters rearranged gives 'TURNCOAT'.
(Other definitions for turncoat that I've seen before include "'Renegade, traitor (8)'" , "Traitor with inverted garment" , "treacherous as one?" , "Judas" , "One betraying party" .)
