Australia’s Foreign Minister Julie Bishop has announced her resignation from the cabinet.
Her move came as new Prime Minister Scott Morrison prepares to announce his new cabinet after winning a bruising leadership contest on Friday.
Ms Bishop said she had not yet decided whether to stand at the next general election, due in 2019.
She had sought the prime minister’s job after Malcolm Turnbull stood aside, but was eliminated in the first round.
The leadership fight also ended her 11-year tenure as deputy leader of the Liberal Party.
The 62-year-old from Western Australia has been a federal politician for two decades.
“I will remain on the backbench as a strong voice for Western Australia,” she said.
Last week’s leadership crisis arose after Mr Turnbull came under pressure from poor polling and what he described as an “insurgency” by conservative MPs.
The Liberal-National coalition government has only a one-seat majority in parliament, and Labour is ahead in opinion polls, with an election to be held at some point before May 2019.
Peter Dutton, a conservative and former home affairs minister, had unsuccessfully challenged Mr. Turnbull on Tuesday, but his narrow defeat only stoked further discord.
Mr. Morrison, the treasurer, entered the race later in the week after Mr Turnbull lost key backers.
He won the second round of Friday’s internal Liberal Party ballot by 45-40 over Mr. Dutton – who had been Mr. Turnbull’s most vocal threat.
Ms Bishop had been eliminated in a first round of voting.
Mr. Turnbull has signalled he will resign from parliament, which would force a by-election and potentially put the government’s one-seat majority at risk and force the new premier to call early elections.
A former Tourism Australia official, Scott Morrison entered parliament in 2007 and has since held three key ministerial portfolios.
As immigration minister, he drew criticism over the controversial asylum seeker policies and offshore detention centres.
Speaking to reporters after the vote on Friday, Mr. Morrison said he would be working to “bring our party back together which has been bruised and battered this week” and bring the country together.
He also said dealing with a severe drought, which has hit parts of eastern Australia, would be “our most urgent and pressing need right now.”
