Dutch city bank headed by a rascal (9)
I believe the answer is:
rotterdam
'dutch city' is the definition.
(I've seen this in another clue)
I can't explain the rest of the clue.
Can you help me to learn more?
(Other definitions for rotterdam that I've seen before include "One of the world's largest ports" , "city abroad" , "Netherlands port" , "European port" , "foreign city" .)
