Vatican pronouncement is full of holes notice (4,3)
I believe the answer is:
holy see
'vatican' is the definition.
(I've seen this before)
'pronouncement is full of holes notice' is the wordplay.
I cannot quite understand how this works, but
'of' could be 'o' and 'o' is located in the answer.
'notice' could be 'see' (notice can mean to spot or see) and 'see' is present in the answer.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for holy see that I've seen before include "Jurisdiction of the Pope" , "place where RC governs" , "Rome ecclesiastically" , "Pope's position" , "Papal office" .)
