No longer done (5)
I believe the answer is:
passe
'no longer done' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for passe that I've seen before include "-- -partout" , "Master key - picture mounting" , "Outdated" , "Out-of-date (French)" , "Old fashioned - in France" .)
