Educated Conservative is livid, unfortunately, about Spain (9)
I believe the answer is:
civilised
'educated' is the definition.
('educated'->'civilized' is in my internal thesaurus and 'ize'->'ise')
'conservative is livid unfortunately about spain' is the wordplay.
'conservative' becomes 'c' (abbreviation commonly used in UK politics).
'unfortunately' is an anagram indicator.
'about' means one lot of letters goes inside another.
'spain' becomes 'e' (abbreviation for Espana).
'c'+'is'+'livid'='cislivid'
'cislivid' is an anagram of 'civilisd'.
'civilisd' placed around 'e' is 'CIVILISED'.
(Other definitions for civilised that I've seen before include "Polite - refined" , "Socially and culturally developed" , "Developed, cultured" .)
