Premier Dominic Perrottet has snapped at journalists asking questions about his brother who has failed to turn up to a NSW parliamentary inquiry into allegations of impropriety at a Sydney council.
"Leave my family out of it. Seriously," the premier told journalists at a press conference in Leppington in western Sydney on Thursday.
NSW upper house MPs have engaged professional help to track down his brother Jean-Claude Perrottet who is wanted to give evidence at the inquiry into allegations of impropriety at the Hills Shire Council.
Mr Perrottet says he hasn't spoken to his brother and doesn't know where he is.
The inquiry has also requested to speak another of the premier's brothers, Charles Perrottet, although he is not able to be summonsed, as he lives in Victoria.
Businessman Frits Mare told a NSW parliamentary inquiry on Wednesday the premier's 26-year-old brother Jean-Claude and Hills Shire Councillor Christian Ellis asked him for $50,000 in 2019.
He said the payment was to "get rid of (Liberal MP) Alex Hawke, stack his seat".
The premier says the inquiry is a political hatchet job cooked up by Labor to smear him in the lead-up to next month's election.
"This is a political inquiry by Labor. We're focused on families in western Sydney," Mr Perrottet said.
As questions over the whereabouts of Jean-Claude continued, Mr Perrottet threw his hands in the air in frustration.
"I'm here elected to represent the people of NSW," he said.
"The Labor Party are playing smear games with my family."
The premier dismissed questions about whether the upper house inquiry was sparked by comments from Liberal MP and Castle Hill MP Ray Williams.
"Ray Williams never raised issues with my siblings in the parliament. He did not," Mr Perrottet said.
"So leave my family out of it.
"If you want to focus on my family, like Labor, go for your life."
The probe is examining matters raised under parliamentary privilege by Mr Williams in June, alleging several senior members of his party were paid to install new councillors who would be friendly to Sydney developer Jean Nassif.
Labor MP Penny Sharpe says the inquiry was put together after Mr Williams made serious allegations in the parliament.
"There are three witnesses that have been summonsed to attend the inquiry," she told AAP on Thursday.
"There is still time for them to co-operate and I encourage them to do so."
