The Independent Commission Against Corruption have extended Operation Keppel to include an investigation of Gladys Berejiklian, prompting the former premier to resign from her role.

Ms Berejiklian will front ICAC for 10 days from October 18, to answer questions over whether she breached public trust by helping secret boyfriend and then-Wagga Wagga MP Daryl Maguire secure grant funding for the Australian Clay Target Association and Riverina Conservatorium of Music.

Sydney Morning Herald investigative journalist Kate McClymont told Jim Wilson the announcement of a public inquiry indicates ICAC already has compelling evidence.

“One of the other really interesting things that ICAC is also looking at is whether Gladys Berejiklian turned a blind eye to conduct that … a reasonable person might’ve thought was corrupt.

“Of course they have to hear all the evidence, but obviously they’ve got enough to think that they’ve got to hold a public inquiry … and I think that’s the reason why … [Ms] Berejiklian has stepped down.”

Findings are usually handed down in around six months, Ms McClymont said, but the wait for answers could be indefinite.

“ICAC did an investigation into $100,000 in cash being handed to the Labor Party – that was two years ago, and we haven’t had a public finding.”
