Mr TURNBULL (Wentworth—Prime Minister) (14:13): Sometimes the conduct and tactics of the opposition beggar belief. A moment ago, we just saw the grave faced Leader of the Opposition seek indulgence, contrary to all precedent, to make a statement about North Korea. Then came the turn for them to ask a question, which could have been about North Korea. But, instead, it's asked about the matter of citizenship. As honourable members know, the High Court will be dealing with a number of citizenship matters—I think it is now seven in total—most of which are citizenship-by-descent matters. I hardly think the Manager of Opposition Business has much credibility on this issue when his leader is not even prepared to demonstrate that he has renounced his own British citizenship.
