Condemn publicly (8)
I believe the answer is:
denounce
'condemn publicly' is the definition.
(I've seen this before)
This is all the clue.
(Other definitions for denounce that I've seen before include "Speak publicly against, having cue with no end" , "Hit out at" , "Openly deplore" , "Speak publicly against, censure" , "As threat, identify" .)
