Mr SHORTEN (Maribyrnong—Leader of the Opposition) (14:12): My question is to the Prime Minister. The Prime Minister knows that we have already agreed in principle, and said so publicly, that dual citizens who fight against Australia with a terrorist group should be stripped of their right to be an Australian. So why is the Prime Minister persistently undermining constructive bipartisanship on national security? Honourable members interjecting— The SPEAKER: We are dealing with serious issues and we will have silence so we can hear the answer.
