National spirit of Turkey articulated by Istanbul's leader (5)

I believe the answer is:

iraqi

I'm a little stuck... Click here to teach me more about this clue!

'national' is the definition.
(I've seen this before)

I can't explain the remainder of the clue.

(Other definitions for iraqi that I've seen before include "Foreign citizen" , "Middle East national" , "native of troubled land" , "Citizen of Baghdad, say" , "foreign national" .)

I've seen this clue in The Times.
