Leaders of ministerial team said to be vain (5)
I believe the answer is:
empty
'vain' is the definition.
(I've seen this before)
I don't understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for empty that I've seen before include "Unfilled" , "Vacant - futile - blank" , "Hollow or vacant" , "'. . . . . vessels make the most sound'" , "Vacuous" .)
