Channel Nine’s 60 Minutes has released the full transcript of its interview with the Special Minister of State Mal Brough, which appears to contradict his claim that a key question about his involvement in the Peter Slipper affair was selectively edited.

The Australian Federal Police (AFP) is investigating whether Mr Brough procured Mr Slipper’s diary from James Ashby in 2012, who was the Speaker’s staffer at the time.

In an interview with 60 Minutes in 2014, Mr Brough appeared to admit that he did ask Mr Ashby to obtain copies of the diary for him, but under sustained questioning from Labor on Tuesday, he said, “what was put to air was not the full question”.

The program has since released a full transcript of the interview which shows the journalist Liz Hayes stumbled at the start of the question.

“Um why then also did you um assist, seek well, [plane noise] did you ask James Ashby to procure um copies of Peter Slipper’s diary for for you?” the transcript says Hayes said.

“Yes I did,” Mr Brough replied.

“Why did you do that?” Hayes responded.

“Because I believed Peter Slipper had committed a crime. I believed he was defrauding the Commonwealth,” Mr Brough said.

After watching the unedited version of the interview, shadow attorney-general Mark Dreyfus told Nine News, the stumble did not affect the meaning of the question.

“It’s very clear what he said, it’s a clear answer to a clear question and this was not edited as the Minister suggested,” he told Nine News.

“I don’t see how the Minister can keep his job after that.”

Labor has been relentlessly pursuing Mr Brough over his involvement in the downfall of Mr Slipper and wants him to stand aside while the AFP investigation is underway.

Mr Brough defeated Mr Slipper in the seat of Fisher at the 2013 election but he has consistently denied any wrongdoing.

Earlier on Tuesday, Mr Ashby told Macquarie Radio that Mr Brough “never, never, ever, ever” asked him for copies of the diaries of Mr Slipper.

Mr Ashby now maintains he went to Mr Brough with copies of the diaries.

“I don’t know exactly how that 60 Minutes interview was cut, but obviously it didn’t look good for Mal Brough,” he said.

“But I can assure you that never at any point did Mal Brough ask me for copies of those diaries.”

Mr Ashby also gave an interview to 60 Minutes last year, where he appeared to accept the proposition that Mr Brough asked for the diaries.

“I must admit I was more than willing to assist Mal with the information that he was seeking,” he said in the 60 Minutes interview.
