Federal election 2013 LIVE: Tony Abbott and Kevin Rudd engage in frantic final days of campaigning LABOR made a mistake in switching leaders, says a business leader while Tony Abbott encourages Big Brother housemates to back him and his good-looking daughters. In a pre-recorded message to the Big Brother housemates Mr Abbott says""If you want to know who to vote for I'm the one with the not bad looking daughters, isn't that great?" While his daughters laugh off the remark, they urge the housemates the support their Dad. Roger Corbett says Labor made a mistake switching to Kevin Rudd so close to an election. Meanwhile, Reserve Bank board member Roger Corbett says Mr Rudd's conduct since he was dumped in 2010 has discredited his own leadership. "He's a man that really has done the Labor Party enormous damage, destabilised it and is now wishing to present himself to the Australian people as a prime minister," Mr Corbett told ABC TV. I don't think the Australian people will cop that. But the comments don't worry Mr Rudd: "It's a matter for Mr Corbett. It's a free country, anyone can say what they like," he told the Nine Network today.
