Christopher Luxon is the genuine John Key copy: the fake Gucci bag of a leader fading in the sunlight. Under a bit of pressure, the weak stitching is fraying, the gold lettering is flaking away, but, as Andrea Vance says, it seems not to matter that, in all of this, the National Party has lost its soul. Mr Luxon wrote poetically, and a little bizarrely, of becoming leader that we should not allow the future to happen to us, but we should happen to the future. Well, I think it's Back to the Future for the National Party, because the book ends chillingly: "Pragmatism and a desire to win may paper over cracks, but if Luxon's momentum fails and an impatient caucus looks around for another silver bullet, they will not have to search far. Waiting in the wings is another disciple of Key in Nicola Willis. 'Willis is there thinking about her future,' a senior MP says. 'She is deeply tactical.' "
