Rescue men I deport in error (10)
I believe the answer is:
redemption
'rescue' is the definition.
(redemption is a kind of rescue)
'men i deport in error' is the wordplay.
'in error' is an anagram indicator.
'men'+'i'+'deport'='menideport'
'menideport' anagrammed gives 'REDEMPTION'.
(Other definitions for redemption that I've seen before include "Salvation, deliverance" , "Act of saving from evil" , "Action of saving from evil" .)
