Two Declaration signers (4)
I believe the answer is:
lees
'two declaration signers' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for lees that I've seen before include "Grounds" , "Dregs left by eels" , "Sediment that settles at the bottom of wine" , "Wine dregs" , "Sediment from wine or beer production" .)
