Powerful men on board here in New York? (6)
I believe the answer is:
queens
I believe this is a double definition.
'powerful men on board' is the first definition.
(I've seen this before)
'here in new york?' is the second definition.
(I know that Queens is a borough of New York City)
(Other definitions for queens that I've seen before include "Belfast university" , "Brooklyn's neighbour" , "Borough of New York City for monarchs" , "promotes man on board" , "Female monarchs" .)
