General pardon making men stay unexpectedly (7)
I believe the answer is:
amnesty
'general pardon' is the definition.
(I've seen this in another clue)
'men stay unexpectedly' is the wordplay.
'unexpectedly' indicates an anagram.
'men'+'stay'='menstay'
'menstay' is an anagram of 'AMNESTY'.
'making' is the link.
(Other definitions for amnesty that I've seen before include "A general pardon as for rebels (7)" , "A general pardon for nasty me" , "suspension of law" , "act of forgiveness" , "When law is suspended" .)
