The LNP opposition has made a failed bid to launch an official probe into Queensland’s corruption watchdog over abandoned fraud charges levelled at seven Logan city councillors. 

A lack of evidence led the Director of Public Prosecutions to drop charges against the former Logan councillors last week, almost two years after they were suspended for an alleged plot to oust the council’s then-chief executive. 

The inquiry would have included public hearings and would have the power to call witnesses to give evidence, and a key union is set to continue pushing the issue again at the ALP state conference next month.
