Restructuring ignored French department (7)
I believe the answer is:
gironde
'french department' is the definition.
(I've seen this before)
'restructuring ignored' is the wordplay.
'restructuring' indicates anagramming the letters.
'ignored' is an anagram of 'GIRONDE'.
(Other definitions for gironde that I've seen before include "Region of France" , "Origin of claret" , "French department around Bordeaux" , "French river" .)
