Former New South Wales Treasurer Matt Kean has resigned from state politics to pursue a career in the private sector.
The Liberal MP had served as the state member for the Northern Sydney electorate of Hornsby for 13 years.
Mr Kean dispelled rumours he would be pursuing a career in federal politics and instead announced he would be moving into the energy industry.
The outgoing MP also criticised the current state Labor government's new budget which he labelled 'the worst in modern history'.
