Untidy person content to leave India for European country (8)
I believe the answer is:
slovenia
'for european country' is the definition.
(country in Europe)
'untidy person content to leave india' is the wordplay.
'untidy person' becomes 'sloven' (I've seen this in another clue).
'content to leave' means to remove the middle letters (the contents of the word are removed).
'india' with its middle removed is 'ia'.
'sloven'+'ia'='SLOVENIA'
(Other definitions for slovenia that I've seen before include "Country with access to Adriatic" , "in E" , "European country, capital Ljubljana" , "Central European republic, became independent in 1991" , "State" .)
