I rise on a point of order, Madam Deputy Speaker, under standing order 90. The member for Wentworth, I believe, imputed an improper motive to the Treasurer when he used the term ‘knave’. ‘Knave’ has a very clear meaning in the English language. I would seek your guidance, because I do not think that personal reflections are appropriate. While I understand that the member for Wentworth has been in this place longer than I have, I expect a better standard of argument from him.
