Man of intelligence moves centre stage (6,5)
I believe the answer is:
secret agent
'man of intelligence' is the definition.
The answer and definition can be both people as well as being singular nouns.
Perhaps you can see an association between them that I don't see?
'moves centre stage' is the wordplay.
'moves' is an anagram indicator.
'centre'+'stage'='centrestage'
'centrestage' anagrammed gives 'SECRET AGENT'.
Can you help me to learn more?
(Other definitions for secret agent that I've seen before include "Conrad character" , "Spy" , "007 - centre stage (anag)" .)
