Get rid of English border - not available in Spain (9)
I believe the answer is:
eliminate
'get rid' is the definition.
(I've seen this before)
'english border not available in spain' is the wordplay.
'english' becomes 'e' (abbreviation).
'border' becomes 'limit' (I've seen this before).
'not available' becomes 'na' (abbreviation for not available).
'in' is an insertion indicator.
'spain' becomes 'e' (abbreviation for Espana).
'limit' enclosing 'na' is 'liminat'.
'e'+'liminat'+'e'='ELIMINATE'
'of' is the link.
(Other definitions for eliminate that I've seen before include "Knock out" , "Exclude from further stage of competition" , "Reject" , "defeat" , "put out" .)
