Senator BIRMINGHAM (South Australia) (12:19): Mr President, I seek leave to make a short statement. The PRESIDENT: Leave is granted for two minutes. Senator BIRMINGHAM: I simply wish to associate the coalition with the remarks of Senator Singh. As she indicated, this is a motion that was passed in the House of Representatives this week with the support of all sides. This is an issue that has long been bipartisan. As Mr Abbott said in the House of Representatives, 'Nuclear weapons cannot be uninvented, but they can be and should be controlled and reduced.' That is certainly our aim. We very much support the intent of this motion and are pleased that it will have the support to pass both houses.
