CANBERRA (Reuters) – Australian Treasurer Scott Morrison will become Australia’s new prime minister after winning a Liberal party leadership vote today, ending an internecine battle that has scarred the conservative government ahead of an election due by May 2019.

Morrison, who will be Australia’s sixth prime minister in less than 10 years, emerged victorious from a three-way race with former home affairs minister Peter Dutton and Foreign Minister Julie Bishop.

Incumbent Prime Minister Malcolm Turnbull, who called the leadership meeting after losing the majority support of the party, opted not to contest the vote. Turnbull told reporters after the vote he would leave parliament “not before too long”.

The Liberal party is the senior partner in the conservative Liberal-National coalition government that has consistently trailed opposition Labor in opinion polls in recent months.

The leadership battle was sparked on Tuesday by an unsuccessful challenge by Dutton, who narrowly lost a vote against Turnbull.

Under intense pressure to call a second vote, Turnbull convened a party meeting on Friday after receiving a letter signed by the majority of party members calling for a change of leader.

Turnbull’s decision to leave parliament means the new government will face a by-election for his Sydney seat that could see it lose its one-seat majority.

Australian media reported that foreign minister Bishop, having been defeated in the leadership ballot, would also likely resign from politics.
