Clue man’s worked out for “America” (5,3)
I believe the answer is:
uncle sam
'for america' is the definition.
(I've seen this before)
'clue man's worked' is the wordplay.
'worked' indicates anagramming the letters.
'clue'+'mans'='cluemans'
'cluemans' with letters rearranged gives 'UNCLE SAM'.
'out' is the link.
(Other definitions for uncle sam that I've seen before include "US government personified" , "Personification of USA" , "national representative, initially appropriate" , "America as a recruiting officer" , "Avuncular appellation for USA" .)
