Little time free for officer abroad (7)
I believe the answer is:
mountie
'officer abroad' is the definition.
(member of the Royal Canadian Mounted Police)
'little time free' is the wordplay.
'little time' becomes 'mo' (I've seen this in other clues).
'free' becomes 'untie' (I've seen this before).
'mo'+'untie'='MOUNTIE'
'for' is the link.
(Other definitions for mountie that I've seen before include "Canadian policemen" , "The lawman always gets his man!" , "Member of the Royal Canadian Mounted Police" , "Horse-riding Canadian cop" , "One boasting of getting man" .)
