Doesn't deny the right of entry (6)
I believe the answer is:
admits
I'm afraid I can't even guess how this answer relates to the clue.
Can you help me to learn more?
(Other definitions for admits that I've seen before include "Agrees to the truth of something" , "Confesses or allows to enter" , "Takes in" , "Owns up or lets in" , "Allows in or accepts guilt" .)
