Divisions Within Labour On Transmission Gully?

Annette King is working her guts out trying to force through progress on Transmission Gully and other roading projects in the Wellington region. But has Grant Roberston just kicked her in the guts with this less than fulsome support for this project (at a minimum he seems to be sitting on the fence)? Does this indicate that Grant is worrying about his chances of winning and is he seeing the need to fight in Green territory? Interesting.....Darren Hughes won't be that pleased to be reading this.
