The man is after Swiss currency (7)
I believe the answer is:
francis
'the man' is the definition.
(I've seen this before)
'is after swiss currency' is the wordplay.
'after' is a charade indicator (letters next to each other).
'swiss currency' becomes 'franc' (I've seen this in another clue).
'is' after 'franc' is 'FRANCIS'.
(Other definitions for francis that I've seen before include "Man" , "Patron saint of animals" , "Assisi saint" , "Sir - - Drake" , "Pope" .)
