Leave Indian State by road (2,4)
I believe the answer is:
go away
'leave' is the definition.
('go away' can be a synonym of 'leave')
'indian state by road' is the wordplay.
'indian state' becomes 'goa' (I've seen this before).
'by' says to put letters next to each other.
'road' becomes 'way' (I've seen this in other clues).
'goa'+'way'='GO AWAY'
(Other definitions for go away that I've seen before include "Disappear" , "Leave" , "Scram" , "Depart" , "Push off" .)
