Let me start with just a comment that the integrity of Parliament as an institution is very much informed by the integrity of both the rules that govern parties and people here and the parties and people themselves. I have been alarmed in this debate by some pretty flippant discussion about people's motivations, particularly in relation to donations. I would say that everyone here takes very seriously the role of parliamentarians in maintaining the integrity of this place, and that, really, what we're having here is a discussion about the problem that we're trying to solve, because we agree, I think, around the House that we do have an issue with public perceptions around the transparency of donations and that we all want a system that people have trust and confidence in.
