This time last year a rift opened between Labour and the Greens. It dogged them through the election campaign and docked votes from both.
For the Greens, it also wiped hopes of cabinet seats. It meant less influence, since Labour can get a majority without them.
The rift was over genetic modification (GM) and was triggered by the Greens’ well-foreshadowed (but nevertheless surprising to Labour) walkout on the bill which legislated an end this coming October to the moratorium an applications for release of GM organisms.
