In a statement MP Matt Kean said: "I have decided not to throw my hat in the ring for the NSW Liberal leadership.

I have a young family and I would love to spend a little more time with them. The election result will enable me to do that.

Tommy recently turned three and now is the time for me to hang out and be a dad, while also continuing to serve my wonderful Hornsby constituents and the Liberal Party, though not as leader and not as part of the leadership team.

I want to thank Dominic Perrottet for his service to the people of NSW and thank my community for their ongoing support. I will continue to work hard for Hornsby every single day.
