Powerful figures on board in New York borough (6)
I believe the answer is:
queens
'new york borough' is the definition.
(I've seen this before)
I cannot understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for queens that I've seen before include "Belfast university" , "part of New York" , "powerful men on board" , "Brooklyn's neighbour" , "College - New York borough" .)
