Northeast Shetland worried about conclusion of mother country (11)
I believe the answer is:
'country' is the definition.
(Netherlands is an example)
'northeast shetland worried about conclusion of mother' is the wordplay.
I cannot quite see how this works, but
'northeast' could be 'ne' (abbreviation) and 'ne' is found in the answer.
'about' could be 'a' (abbreviation in Chambers) and 'a' is found in the answer.
This may be the basis of the clue (or it may be nonsense).
(Other definitions for netherlands that I've seen before include "Their government at The Hague" , "European kingdom, capital Amsterdam" , "a nation" , "North European country" , "- Antilles includes island of Curacao" .)
