Outfit used in endless sex found by southern police abroad (9)
I believe the answer is:
gendarmes
'police abroad' is the definition.
'Gendarmes' can be an answer for 'police' (branch of French police). I'm unsure of the 'abroad' bit.
'outfit used in endless sex found by southern' is the wordplay.
I cannot really see how this works, but
'outfit' could be 'arm' (I've seen this in another clue) and 'arm' is present in the answer.
'southern' could be 's' (abbreviation) and 's' is present in the answer.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for gendarmes that I've seen before include "French policemen" , "soldiers" .)
