Liberal going after a job meets European advocate (7)
I believe the answer is:
apostle
'advocate' is the definition.
(the apostles were advocates of Jesus)
'liberal going after a job meets european' is the wordplay.
'liberal' becomes 'l' (abbreviation).
'going after' is a charade indicator (letters next to each other).
'job' becomes 'post' (post is a kind of job).
'meets' says to put letters next to each other.
'european' becomes 'e' (abbreviation e.g. EU).
'a' next to 'post' is 'apost'.
'l' after 'apost' is 'apostl'.
'apostl'+'e'='APOSTLE'
(Other definitions for apostle that I've seen before include "Thaddeus, perhaps" , "St James, for example" , "Principal champion" , "Chosen disciple" , "Religious messenger" .)
