Cleverly, say, incriminate best shot (7,8)
I believe the answer is:
cabinet minister
'cleverly say' is the definition.
Although both the answer and definition are singular nouns, I cannot see how one could define the other.
'incriminate best shot' is the wordplay.
'shot' is an anagram indicator.
'incriminate'+'best'='incriminatebest'
'incriminatebest' anagrammed gives 'CABINET MINISTER'.
Can you help me to learn more?
(Other definitions for cabinet minister that I've seen before include "member of government" , "May perhaps" , "went down to provide 22 24 [WHISKY GALORE] - with 17d" , "high-ranking member?" , "senior politician" .)
