The Times reported on a call for Main Roads WA to take over the City's Flynn Drive realignment project on May 26, which coincided with a confidential report about it on that night's council meeting agenda.
The story prompted speculation that there had been a breach of confidence by councillor Linda Aitken at a Two Rocks Yanchep Residents Association (TRYRA) meeting the night before.
