One northern viewpoint, for example (8)
I believe the answer is:
instance
'example' is the definition.
(I know that example can be written as instance)
'one northern viewpoint' is the wordplay.
'one' becomes 'i' (Roman numeral).
'northern' becomes 'n' (abbreviation e.g. N. Ireland).
'viewpoint' becomes 'stance' (I've seen this before).
'i'+'n'+'stance'='INSTANCE'
'for' is the link.
(Other definitions for instance that I've seen before include "An insect (anag.)" , "Particular example" , "Particular case; cite" , "Cite as an example" , "Case - isn't acne (anag)" .)
