The NSW Treasurer Matt Kean is the new deputy leader of the state's Liberal Party.
Kean was elected unopposed in a partyroom meeting this morning.
The decision comes after former deputy leader Stuart Ayres resigned last week.
The deputy leadership bid for Kean was successful at just after 10 am this morning, according to the government whip, Nathaniel Smith.
"I'm happy to announce that there was only one candidate who stood for election," he said.
Our new deputy leader of the parliamentary Liberal Party, who was elected unopposed, is Matthew Kean, member for Hornsby, Treasurer of New South Wales and Minister for Energy. Ayres stepped down from his deputy leader and ministerial positions last week due to the fallout of former deputy premier John Barilaro's appointment to a US-based trade role.
An independent inquiry into the recruitment process, ordered by Premier Dominic Perrottet, raised questions as to whether Mr Ayres had breached the Ministerial Code of Conduct.
Transport Minister David Elliott, a close friend of Transport Minister Ayres, had flagged his intention to run for the deputy leadership but pulled out of the race yesterday.
Mr Elliott told 2 GB that he withdrew at the request of Mr Perrottet, who he said had laid down a demand for unity ahead of today's meeting.
I told him that he respects his wish to pick his own deputy, Mr Elliott said.
The media is expected to hear from Mr Perrottet and Mr Kean at noon today.
