Follow Europe’s directions to return (5)
I believe the answer is:
ensue
'follow' is the definition.
(I've seen this before)
'europe's directions to return' is the wordplay.
'europe's' becomes 'eus' (European Union).
'directions' becomes 'ne' (I've seen this in other clues).
'to return' says the letters should be written backwards.
'eus'+'ne'='eusne'
'eusne' back-to-front is 'ENSUE'.
(Other definitions for ensue that I've seen before include "Proceed" , "Come along afterwards" , "Occur as a result (of)" , "Follow later" , "Happen as consequence or afterward" .)
