The MP - National's David MacLeod - says that it is because he misunderstood the law. Which really makes you worry about whether he is properly understanding the laws he is voting on. He has been stood down from his committee positions, but it is not enough. Because filing a false donation return isn't just a mistake - it is a crime. And one that is utterly inconsistent with remaining in Parliament. MacLeod should resign. If he does not, it will tell us something significant about his, and his party's, attitude to electoral fraud.
