The deputy leader and treasurer ran unopposed for the job, so no vote was held.

Two other contenders for the job, planning minister Rob Stokes and transport minister Andrew Constance ruled out a challenge, clearing the path for Berejiklian to become the state's third premier in three years.



Finance minister Dominic Perrottet, from the party's Right, was elected deputy leader. National John Barilaro remains the Coalition's deputy leader.

The daughter of Armenian migrants, Berejiklian has held the northern Sydney seat of Willoughby since 2003.



Berejiklian is a moderate from the Left faction of the Liberal party, which means on many issues she is socially progressive and economically conservative. She supports same-sex marriage, is reportedly compassionate towards the plight of refugees but has never given a public opinion about Sydney's controversial lock out laws.
