Australia’s conservative leader Tony Abbott swept into office today in a landslide election after incumbent prime minister Kevin Rudd conceded defeat, the Telegraph reported.The Australian Broadcasting Corporation on Saturday called a clear win for the Abbott-led opposition party over Mr Rudd’s Labour in national polls. Meanwhile a government minister said her party had lost the election. Health Minister Tanya Plibersek told ABC after 13 percent of the votes were counted that her government’s loss was no longer in doubt. “The coalition is on a pretty secure 74 seats already. On that basis they’re going to get a majority. I think we can say the government has been defeated,” Antony Green, the state broadcaster’s election analyst, said. She said: “I am a cautious person by nature, but I think that it’s pretty clear it’s a matter of the size of the victory” for the conservative Liberal Party-led alliance.The apparent victory by Australia’s British-born opposition leader would mark a dramatic return to power for the conservative Liberal-National party after six years of shaky Labour rule. Rudd has only been in office for three months after defeating Julia Gillard, Australia’s first female prime minister, in a leadership challenge. Gillard ousted Mr Rudd as leader during his first term in 2010.Though Mr Abbott ran a strong campaign, Australians have not yet completely warmed to him.
