A country seat? No, I suspect (7)
I believe the answer is:
estonia
'a country' is the definition.
(I've seen this before)
'seat? no i suspect' is the wordplay.
'suspect' indicates anagramming the letters.
'seat'+'no'+'i'='seatnoi'
'seatnoi' is an anagram of 'ESTONIA'.
(Other definitions for estonia that I've seen before include "East European country" , "Northern European country" , "Country on the Baltic Sea" , "Baltic state" , "Country due S. of Finland" .)
