Mar McGowan’s long-time advisor Guy Houston told Millsy and Karl on 6PR Breakfast he was told the Premier would be stepping down about two weeks ago.

Mr Houston has been a Labor stalwart for decades, having been next to Mr McGowan during his election as Member for Rockingham and subsequent rise to Premier.

“He confided in me a couple of weeks ago that he was considering it,” Mr Houston said.

“We ran through all the pros and cons. He’d made up his mind.”
