Nation somehow “discontented”, PM concludes (6)
I believe the answer is:
sweden
'nation' is the definition.
(Sweden is an example)
'somehow discontented pm concludes' is the wordplay.
'discontented' says to hollow out the word (remove centre letters) (the word's contents are removed).
'pm' becomes 'Eden' (former prime minister Anthony Eden).
'concludes' means one lot of letters go next to another.
'somehow' with its middle taken out is 'sw'.
'sw'+'eden'='SWEDEN'
(Other definitions for sweden that I've seen before include "EU member country" , "European kingdom" , "Baltic country" , "4's neighbour" , "We send out to the northern state" .)
