Characters from Norfolk now nationally famous (5)
I believe the answer is:
known
'famous' is the definition.
(similar in meaning)
'characters from norfolk now nationally' is the wordplay.
'characters from' indicates a hidden word.
'KNOWN' is hidden within 'norfolk now nationally'.
(Other definitions for known that I've seen before include "Famous" , "Acknowledged" , "In the public domain?" , "Within one's ken" , "Widely recognised" .)
