Snob, cad, forced to leave secretly (7)
I believe the answer is:
abscond
'leave secretly' is the definition.
(I've seen this before)
'snob cad forced' is the wordplay.
'forced' indicates an anagram.
'snob'+'cad'='snobcad'
'snobcad' anagrammed gives 'ABSCOND'.
'to' is the link.
(Other definitions for abscond that I've seen before include "Depart without permission" , "Leave quickly and secretly" , "Escape, flit" , "Run away secretly" , "make quick getaway" .)
