God's part within the welfare state (4)
I believe the answer is:
ares
'god's' is the definition.
(Greek god of war)
'part within the welfare state' is the wordplay.
'part' indicates a hidden word.
'ARES' can be found hidden inside 'within welfare state'.
(Other definitions for ares that I've seen before include "War-god" , "Olympian" , "Greek god of war" , "Land measures" , "figure of worship" .)
