Gauleiter, losing province after return, secure again (5)
I believe the answer is:
retie
'secure again' is the definition.
('tie' is an answer for 'secure' so perhaps 'retie' is OK for 'secure again')
'gauleiter losing province after return' is the wordplay.
'RETIE' is hidden back-to-front in amongst the letters.
However, I am unsure how the hidden word is indicated.
Can you help me to learn more?
(Other definitions for retie that I've seen before include "Bind again" , "make another knot" , "Link up again" , "restore connection" , "Make knot or bow again" .)
