Exchange of prisoners rejected (4)
I believe the answer is:
swop
'exchange' is the definition.
(swop is a kind of exchange)
'prisoners rejected' is the wordplay.
'prisoners' becomes 'pows' (POW is an example).
'rejected' says the letters should be written backwards.
'pows' reversed gives 'SWOP'.
'of' acts as a link.
(Another definition for swop that I've seen is " Exchange (Alt sp.)".)
I've seen this clue in The Guardian.
Want a hint initially instead of a full solution?
