Gladys Berejiklian has revealed that she will be stepping down as premier of New South Wales over her relationship with Daryl McGuire.
She is also resigning from NSW politics, triggering a by-election.
The Independent Commission Against Corruption said in a statement on Friday that it was investigating whether Ms Berejiklian “exercised public functions” in a position of conflict between her public duties and private relationship with Mr Maguire, revealed in late 2020.
A public inquiry on the matter will be held from October 18, overseen by ICAC Assistant Commissioner Ruth McColl SC.
It is expected to last about 10 days.
ICAC said Ms Berejiklian would be investigated over grant funding to the Australian Clay Target Association in 2016/17 and grant funding to the Riverina Conservatorium of Music in Wagga Wagga in 2018.
It plans to look into whether Ms Berejiklian’s relationship with Mr Maguire, then the Wagga Wagga MP, affected those arrangements and constituted a breach of public trust or partial exercise of official functions.
ICAC will also investigate whether Ms Berejiklian should have “suspected on reasonable grounds” that Mr Maguire may have engaged in corrupt conduct, and thus failed to report him to ICAC as required.
It will look into whether she “was liable to allow or encourage” his conduct.
