QUEENSLAND Liberal MP Mal Brough was the mysterious “Jackie’’ who organised a lawyer for former Speaker Peter Slipper’s staffer weeks before he lodged the sexual harassment case that threatened to bring down the Gillard government.

James Ashby makes the allegations in a tell-all interview tonight on 60 Minutes which is billed as containing allegations of a “secret plot that will rock the Abbott Government”.

Channel 9 has refused to disclose whether Mr Ashby was paid for the interview.

Questioned by Liz Hayes, Mr Ashby confirms that Mr Brough is the mystery female called Jackie he referred to in text messages with another staffer, Karen Doane.

In the text messages, Mr Ashby says that “Jackie’’ was an influential figure who helped organise a lawyer for him and could help the pair get new jobs.

“Jackie was Mal Brough,’’ Mr Ashby says. “I’d received a phone message … one day and it said ‘contact Jackie’ and I rung the number, didn’t register with me who it was and a woman answered the phone and I said ‘Oh hi, is Jackie there’ and she said ‘I’ll put him on,’’ Mr Ashby said.

“And before I knew it, Mal Brough picked up the phone. He just kept the name … There’s been plenty of names thrown about, but the reality was it was always Mal Brough.”

Mr Brough has previously admitted bringing LNP supporter David Russell QC, to a meeting with Mr Ashby, who advised him he “might have a case for sexual harassment’’ against Mr Slipper.

Mr Brough, who was interviewed for the program, said he had no idea he was “Jackie’’ in the text messages.

“I’m Jackie? That explains why no one ever knew who Jackie was,’’ he said yesterday.

“The only lawyer I organised was David (Russell QC) who met him once,’’ Mr Brough said.

Mr Ashby also claims that Mr Slipper ordered him not to use his real name in taxis.

“I remember the very first time we caught a cab, I said ‘where are we off to, Peter?’ and afterwards when we got out, he said to me to never call him Peter Slipper or his real name any time we travel in cabs.”

Education Minister Christopher Pyne, who emailed Mr Ashby after drinks in the Speaker’s office, will also feature in the 60 Minutes investigation.
