The head of Queensland's Crime and Corruption Commission (CCC) has resigned following increasing pressure for him to quit the role.

Alan MacSporran said he had today advised the Attorney-General that he would resign from the position as chairperson effective from this Friday.

"Many people have urged me to continue in this important role, despite the recent finding contained in the report of the Parliamentary Crime and Corruption Committee (PCCC)," he said in a statement.

"However, I find myself in a position where, despite a career spanning in excess of 40 years, where my honesty and integrity have never been questioned, it is clear to me that the relationship between myself and the PCCC has broken down irretrievably.

"This saddens me deeply."

His resignation comes after a parliamentary committee last year recommended a commission of inquiry be held into the CCC's structure after finding it breached its duty to remain independent and impartial.

The recommendation was made after the bipartisan committee looked into the CCC's decision to charge eight Logan City councillors with fraud in 2019.

The PCCC also found the CCC discretion to charge the councillors miscarried "because all material considerations and evidence were not taken into account and weighed".

The fraud charges, which prompted the entire council's dismissal, were discontinued in a Brisbane court in April, almost two years later.

In final submissions in October, the counsel assisting had suggested the possibility of recommending parliament terminate Mr MacSporran's appointment.

PCCC chair Jon Krause told the house it did not proceed with that recommendation and said it was of the view "this report speaks for itself".

Mr MacSporran defended his time in the role and said he came to the position with decades of experience in the criminal justice system.

"In my long career, I have never, ever, let extraneous irrelevant considerations enter my thinking about a decision relating to the proper exercising of powers in proceedings as a Queen's Counsel criminal barrister or as CCC Chairperson," he said.

"Investigating corruption and major crime is inherently complex.

"Those who are the subject of allegations and subsequent investigations can be persons with a high public profile. They frequently hold positions of power and the consequences of charges, let alone conviction, can be particularly grave.

"I understand this, as do all CCC officers. However, the Queensland community rightly expects the CCC to do its statutory job, and that ultimately involves making very complex, tough and independent decisions as an investigative agency.

"As Chairperson, I was willing to make, and support my staff making, those independent decisions."

MacSporran 'exceptionally priveleged' to take on 'challenging' role

Mr MacSporran said he had been "exceptionally privileged" to have led the CCC.

"The role of chairperson is challenging, and I will always consider myself to have been exceptionally privileged to have led it for the time I have," he said.

"The CCC is greater than the sum of its parts and I wish the agency every success in the future while it continues its essential role of combating major crime and reducing corruption for the benefit of all Queenslanders. "

Mr MacSporran was named as head of the CCC by Premier Annastacia Palaszczuk in July 2015. 

He previously led the Queensland government's inquiry into the greyhound racing industry and served in the oversight role of parliamentary crime and misconduct commissioner.

Mr MacSporran also represented the state of Queensland at the Queensland Floods Commission of Inquiry and the Queensland Health Payroll System Commission of Inquiry.
