CANBERRA, Aug. 24 (Xinhua) -- Scott Morrison won a party ballot to become Australia's new prime minister on Friday after defeating Peter Dutton and Foreign Minister Julie Bishop in the leadership vote of the governing Liberal Party.

Morrison defeated Dutton, former minister of home affairs and the most senior conservative member of the government, in the ballot by 45 votes to 40.

Bishop was eliminated in the first round of voting as she received the fewest number of votes.

Malcolm Turnbull resigned as prime minister after 45 of the 85 Liberal Party Members of Parliament (MPs) voted to vacate the leadership at the meeting and intended to resign from the parliament.

It came just days after Turnbull defeated Dutton 48-35 in a ballot on Tuesday.

Energy and Environment Minister Josh Frydenberg was elected deputy leader of the party, taking over from Bishop.
