Hanoverian monarch — not English — leading a Eurasian country (7)
I believe the answer is:
georgia
'eurasian country' is the definition.
(Georgia is in Eurasia)
'hanoverian monarch not english leading a' is the wordplay.
I cannot quite see how this works, but
'monarch' could be 'r' (abbreviation for rex, king in Latin) and 'r' is present in the answer.
'not' could be 'o' (I've seen this in other clues) and 'o' is located in the answer.
'english' could be 'e' (abbreviation) and 'e' is present in the answer.
'a' is found in the answer.
This may be the basis of the clue (or it may be nonsense).
(Other definitions for georgia that I've seen before include "Southern US state" , "US state -- Black Sea state" , "Female" , "A US state; a country" , "Its capital is Tbilisi (or Atlanta)" .)
