Overseas police turning out seem grand (9)

I believe the answer is:

gendarmes

'overseas police' is the definition.
(branch of French police)

'turning out seem grand' is the wordplay.
'turning out' indicates an anagram.
'seem'+'grand'='seemgrand'
'seemgrand' is an anagram of 'GENDARMES'.

(Other definitions for gendarmes that I've seen before include "French policemen" , "soldiers" .)

I've seen this clue in The Guardian.
