The only change will be that Environment Minister Matt Kean will also take on Mr Perrottet’s previous responsibilities as treasurer. Mr Kean’s promotion to the key portfolio was part of a deal struck by Liberal powerbrokers to ensure Mr Perrottet had enough votes to become leader.

Mr Perrottet said he expects to reshuffle the cabinet over summer. He said Mr Stokes remains a good friend and will continue to play a key role in the government.

Following the vote,Mr Stokes said Mr Perrottet has his “undivided loyalty and support”.

“The party room had a democratic vote,” Mr Stokes said. “I always said that I’d give my people a choice. They have chosen emphatically.

“Democracy is the winner today.”

Mr Stokes said Mr Perrottet will be “a magnificent premier”,committing to work hard to ensure the government is re-elected when NSW next goes to the polls in 2023.

Asked if he would seek a position in a new cabinet,Mr Stokes said it was “entirely a matter for the premier,but he has my support”.

Health Minister Brad Hazzard,who was one of the last to leave the party room meeting,said he welcomed Mr Perrottet’s win.

“What matters is that we have a premier now who will make sure the citizens of the state are well cared for,” Mr Hazzard said.

Tuesday’s vote followed the shock resignation of Gladys Berejiklian as premier on Friday.

Ms Berejiklian quit as premier and announced she would leave NSW Parliament after the Independent Commission Against Corruption said it was investigating whether she breached the public trust or encouraged the occurrence of corrupt conductduring her secret relationship with disgraced former MP Daryl Maguire.

Ms Berejiklian had been expected to attend Tuesday’s meeting to address the party for a final time as leader but she did not attend and did not cast a vote.

A Liberal MP said the party room acknowledged Gladys Berejiklian’s time as premier and the “sad circumstances” of her departure amid the ICAC investigation.

“We are all locking in together behind Dom,” the MP said.

Another MP said Mr Perrottet addressed the party room after he won the vote and promised to fight for every community in NSW.

NSW Labor leader Chris Minns has contacted Mr Perrottet to offer his congratulations on his election to the top job.
