Clear policy statement is not finished (8)
I believe the answer is:
manifest
'clear' is the definition.
(synonyms)
'policy statement is not finished' is the wordplay.
'policy statement' becomes 'manifesto' (statement of political policies).
'is not finished' means to remove the last letter.
'manifesto' with its last letter taken off is 'MANIFEST'.
(Other definitions for manifest that I've seen before include "Ship's document; plain" , "Evident" , "List of ship's cargo or passengers" , "(Of ghost) appear" , "Express" .)
