Liberal MPs have endorsed Gladys Berejiklian as the 45th premier of NSW, the state’s seventh premier in 12 years.

She won the unanimous support of her bitterly divided party after agreeing to scrap policies she previously favoured and handing out cabinet positions to her bitterest opponents in the hard-right faction. By attempting a balancing act between party “wets” and “dries”, Berejiklian has created an inherently unstable administration.

Her new deputy Dominic Perrottet, the hard-right’s premier-in-waiting, will become Treasurer and deputy Liberal leader to pursue his philosophy of wholesale privatisation, smaller government and lower taxation for companies and entrepreneurs.
