Republican worried about man shot again? (7)
I believe the answer is:
retaken
'shot again?' is the definition.
('taken' can be a synonym for 'shot' so perhaps 'retaken' is OK for 'shot again')
'republican worried about man' is the wordplay.
'republican' becomes 'r' (abbreviation).
'worried' becomes 'ate' (something worrying may eat someone up).
'about' is a reversal indicator.
'man' becomes 'ken' (**).
'ate' backwards is 'eta'.
'r'+'eta'+'ken'='RETAKEN'
(Other definitions for retaken that I've seen before include "Seized again" , "Recaptured" , "picked up again" , "Captured again" , "shot again?" .)
