Mr DUTTON (Dickson—Minister for Defence and Leader of the House) (14:01): I'm advised the Deputy Prime Minister is the only person who's in that scenario at the moment. We'll make further inquiries. In terms of ministerial arrangements, the member for Bradfield will answer questions on behalf of the Deputy Prime Minister and that's the arrangement that's in place. The SPEAKER: Obviously, in the capacity as Speaker, I can concur with the remarks that have been said. Just before I call the Leader of the Opposition, I remind members that the Serjeant-at-Arms has sent out regular memorandums about the responsibilities that all of us have and to keep up with all of the updates that are there and take the actions that are required.
