Senator MILNE (Tasmania—Leader of the Australian Greens) (14:24): Mr President, I have a further supplementary question. Given the obvious division within the Labor caucus on this issue, with members of the party like Senator Cameron attempting to show a caring side of a government that is refusing to stand up to the mining companies to pay a decent amount so we can meet welfare payments, is the minister aware of any other Labor senators in addition to Senator Cameron who are prepared to cross the floor to put their words into actions to support the Greens' bill to increase Newstart by $50 a week and reverse the cuts to single parents made by Howard's welfare to work laws? The PRESIDENT: The minister can only answer that question in so much as it pertains to the portfolios.
