Cunning statecraft with no rest curiously producing a moneybags (3,3)
I believe the answer is:
fat cat
'a moneybags' is the definition.
(thesaurus)
'cunning statecraft with no rest' is the wordplay.
'cunning' indicates anagramming the letters.
'with no' suggests deleting specific letters.
'statecraft' with 'rest' removed is 'atcaft'.
'atcaft' is an anagram of 'FAT CAT'.
'curiously producing' acts as a link.
This may not be right. Some or all of it may be part of another bit of the clue.
Can you help me to learn more?
(Other definitions for fat cat that I've seen before include "One wealthy, overpaid" , "Magnate" , "(Obscenely) wealthy businessman" , "Big cheese" , "Someone (undeservedly?) rich in business" .)
