Refusal to accept or admit (6)

I believe the answer is:

denial

(Other definitions for denial that I've seen before include "Refusal to acknowledge" , "Declaration that something is untrue" , "Daniel (anag.)" , "Refusal to accept an unpalatable truth" , "Refusal to believe an unacceptable truth" .)

I've seen this clue in the Sydney Morning Herald.
