Consent to overlook a church in European country (6)
I believe the answer is:
greece
'european country' is the definition.
(country in Europe)
'consent to overlook a church' is the wordplay.
'consent to' becomes 'agree' (agreeing is a kind of consenting to).
'overlook' indicates named letters should be taken away.
'church' becomes 'ce' (Church of England).
'agree' with 'a' taken away is 'gree'.
'gree'+'ce'='GREECE'
'in' acts as a link.
(Other definitions for greece that I've seen before include "Bust area" , "Republic whose mythology is widely known" , "European state" , ""The cradle of civilisation"" , "The country sounds slippery" .)
