Country tests for any bias when exposed (7)
I believe the answer is:
estonia
'country' is the definition.
(European country)
'tests for any bias when exposed' is the wordplay.
I cannot really understand how this works, but
'for' could be 'to' (eg both can mean 'in the opinion of') and 'to' is found in the answer.
'when' could be 'e' (I've seen this in other clues) and 'e' is found within the answer.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for estonia that I've seen before include "Land" , "Country on the Baltic Sea" , "'So eat in here in Tallinn, say (7)'" , "Republic in the Baltic region, once part of USSR" , "So eat in poorly on the Baltic Sea" .)
