Level with First Lady (3)
I believe the answer is:
eve
'first lady' is the definition.
(I've seen this before)
'level with' is the wordplay.
'with' says the answer is hidden in the clue.
'EVE' is hidden in the letters of 'level'.
(Other definitions for eve that I've seen before include "Previous day" , "First lady from the night before" , "Adam's partner" , "Later in the day, in short" , "Adam's wife" .)
