So. New Zealand First has fallen in behind Labour's emissions trading scheme, and a more astute political observer than I would have quickly realised that was inevitable after the release of the Owen Glenn letter this morning, which changed the political dynamic completely. Suddenly finding himself vulnerable, Winston Peters was hardly likely to alienate the person whose protection and patronage he most needed by telling Labour to take its ETS and shove it. He's now clinging to the PM in what might be characterised as a death embrace. How long before she prises him loose?
