Zak Kirkup has been elected leader of the opposition unopposed after Dean Nalder withdrew his candidacy earlier this morning.
Mr Nalder, who unsuccessfully challenged then-premier Colin Barnett's leadership in 2016, announced he would contest the leadership on Sunday but withdrew his candidacy earlier this morning.
“It has become apparent that I don’t have the majority support of my parliamentary colleagues and therefore will clear a path for the new leader,” he said.
“I have been humbled at the level of support from my electorate and the wider community.”
Mr Nalder has been approached for further comment.
Mr Kirkup, who was elected to the seat of Dawesville by a narrow margin in 2017 and has held the shadow health portfolio since 2019, will at 33-years of age be the youngest person to lead the Liberal Party WA.
He will be the first leader since Matt Birney to enter the role without any ministerial experience, although he was a political adviser before entering parliament.
Mr Kirkup will replace Liza Harvey, who had served as leader for 17 months before announcing her resignation over the weekend.
Elsewhere, Ms Mettam, who has represented the seat of Vasse since 2014, will replace Bill Marmion as deputy leader.
The opposition now has 109 days to make its case ahead of the state election, in which the incumbent state government is generally favoured to win a second term.
He ruled out shifting to a safer seat ahead of the March election.
