Well it is official. A further poll points to a surge in support for Labour since David Cunliffe became leader.
The latest Roy Morgan poll has Labour on 37% up 4.5%, National on 42% and the Greens on 11% although down 3.5%. National is up slightly to 42%.
I expect support will settle back a little in the next series of polls but I think it can be safely said that National now has a battle on its hands to win the next election.
