Resigns in order to make an entrance (7)
I believe the answer is:
ingress
'an entrance' is the definition.
('ingress' can be a synonym of 'entrance')
'resigns in order' is the wordplay.
'in order' indicates anagramming the letters (the letters in a new order).
'resigns' is an anagram of 'INGRESS'.
'to make' is the link.
(Other definitions for ingress that I've seen before include "Means of access" , "right of entry" , "Entrance, access" , "permission to enter" , "going in" .)
