Capital from bank Arab's withdrawn (6)
I believe the answer is:
ankara
'capital' is the definition.
(Ankara is an example)
'from bank arab's withdrawn' is the wordplay.
'from' says the answer is hidden in the clue.
'ANKARA' is hidden within 'bank arabs withdrawn'.
(Other definitions for ankara that I've seen before include "Capital of 8 across" , "Capital of Turkey" , "Capital established by Ataturk" , "European capital" , "Turkey's capital" .)
