Mr SHORTEN (Maribyrnong—Leader of the Opposition) (14:00): My question is to the Prime Minister. For 18 months the government has been talking about stripping citizenship from dual citizens yet no legislation has been introduced. In fact, the only document we have seen is a leaked, blatantly political, confidential briefing. Giving that this briefing betrays bipartisanship on national security matters, why is the government trying to destroy bipartisanship rather than working together on national security? Opposition members interjecting— The SPEAKER: There will be silence on my left! That includes the Deputy Leader of the Opposition.
