Retract Nancy's article, for instance (5)

I believe the answer is:

unsay

'retract' is the definition.
(thesaurus)

'nancy's article for instance' is the wordplay.
'nancy's article' becomes 'un' (indefinite article in French, eg in Nancy).
'for instance' becomes 'say'.
'un'+'say'='UNSAY'

(Other definitions for unsay that I've seen before include "Recall" , "Take back (words)" .)

I've seen this clue in the Independent.
