Politicians – vegetables (6)
I believe the answer is:
greens
I believe this is a double definition.
'politicians' is the first definition.
(members of the Green Party)
'vegetables' is the second definition.
(I know this)
(Other definitions for greens that I've seen before include "Vegetables - on the golf course?" , "party politicians" , "Signs people should go" , "Nature lovers" , "Ecology party" .)
