Disputed territory of church covering border needing answer (6)
I believe the answer is:
crimea
'disputed territory' is the definition.
(European region of disputed status)
'church covering border needing answer' is the wordplay.
'church' becomes 'CE' (abbreviation for Church of England).
'covering' is an insertion indicator.
'border' becomes 'rim' (I've seen this before).
'needing' says to put letters next to each other.
'answer' becomes 'a' (abbreviation eg in Q and A).
'ce' going around 'rim' is 'crime'.
'crime'+'a'='CRIMEA'
'of' is the link.
(Other definitions for crimea that I've seen before include "Black Sea region" , "High-quality black tea" , "part of the Ukraine" , "Ukrainian peninsula, scene of war" , "former battleground" .)
