Confess and allow access (5)
I believe the answer is:
admit
I believe this clue is a double definition.
'confess' is the first definition.
(I've seen this in another clue)
'allow access' is the second definition.
(I've seen this before)
'and' is the link.
(Other definitions for admit that I've seen before include "Accept" , "Allow entry" , "Agree to the truth" , "Recognise" , "Usher in" .)
