Senate inquiry an expensive stunt: Qld A-G

Queensland's attorney-general has refused to front the Senate inquiry into the state government.

The inquiry chair, Palmer United Party Senator Glenn Lazarus, announced on Wednesday that Attorney-General Jarrod Bleijie had been called to front the next public hearing on Friday.

But Mr Bleijie says he won't be front the inquiry because it's an expensive political stunt.

"I will not be attending the inquiry to give evidence," Mr Bleijie said in a letter to the inquiry secretary.

"Public reports confirm my view that this is a politically motivated inquiry that will not deliver any positive outcomes for Queenslanders.

"I regret that Labor and the Palmer United Party senators continue to pursue this expensive political stunt."

Queensland's government has previously labelled the inquiry, backed by Labor and the Greens, a "witch hunt".

Former solicitor-general Walter Sofronoff, former assistant health minister Chris Davis and independent MP Peter Wellington are also listed to appear at the next public hearing in Brisbane on Friday.

The two previous public hearings have been characterised by coalition committee members arguing, interjecting and bullying witnesses, most of which have links to either Labor or the Greens.
