Sam Groth to exit parliament early and spark costly byelection

Former deputy opposition leader Sam Groth will exit parliament early and force his electorate to the polls just months before the state election.

Groth last month suddenly announced he would retire from politics at the November election, but he will now leave parliament early.

It means his Nepean electorate will go to a byelection in the coming months.

Opposition Leader Jess Wilson is due to address the media later this afternoon.
