The point here is that with a whip system, with a large executive, and with the existence of list MPs, the incentive to go along with the party are already high. But, actually—and this is the point Dr Smith made—we want MPs to sometimes say unpalatable things. Actually, sometimes we want MPs to go against the party line. Actually, I'd be one who would say, looking back with the perspective of history, that, actually, it's a good thing Marilyn Waring spoke up on nuclear ships. Marilyn Waring divorced herself from Mike Moore in relation to rape legislation that was going through the Parliament in the early 1980s, and I think, with the perspective of history, we'd look back and say it was a good thing she said that.
