Craig was author of his own misfortune, jury told

Former Conservative Party leader Colin Craig was the author of his own misfortune, the lawyer for the man suing him has told a court.

Mr Craig is being sued by the founder of the Taxpayers' Union over comments he made in a leaflet and at a news conference in July last year.

The defamation trial against Mr Craig is into its fourth week in the High Court in Auckland and today lawyers for both Mr Craig and Jordan Williams made their closing arguments to the jury.

Read about the Colin Craig defamation case in a nutshell here.

Mr Craig's lawyer, Stephen Mills, told the jury Mr Williams said some seriously damaging things about Mr Craig and the nature of his relationship with his former press secretary, Rachel MacGregor.

"They were not correct. What was said about the non-consensual nature of that election eve incident, that was not correct. What was said about the sex text was not correct.

"What was said about Mr Craig, on more than one occasion, pressuring Ms MacGregor to stay the night was not correct."

By the time he stepped down as the party's leader in June last year, Mr Craig's reputation was shredded and his political aspirations were over, Mr Mills said.

"What happened here was a determined effort by Mr Williams, which he doesn't deny, to have him removed and to do that by putting out rumours and stories and allegations which were not correct in many cases," he said.

"I think the evidence shows clearly [Mr Williams] knew they weren't true ... but he passed it on at any rate and in doing that he was lying."

By publishing the leaflet at the centre of the defamation case, Mr Mills said Mr Craig was responding to an attack on his reputation - standing up for what he thought was the right way of doing politics and going after what he considered the wrong way of doing politics, which he had been the victim of.

But Mr Williams' lawyer, Peter McKnight, said Mr Craig attacked his client's honesty and integrity.

He said there was no evidence that Mr Williams lied.

"He relied on Colin Craig's own words. These were the words of a fundamentally flawed man, somebody who had held himself out as a beacon of moral virtue and family values.

"In fact I suggest to you the evidence demonstrates that Colin Craig is at best a complete hypocrite, at worst somebody who sexually harassed his press secretary and acted dishonourably."

Mr McKnight rejected any suggestions that Mr Williams was to blame for Mr Craig's political downfall.

He said if Mr Craig was looking for someone to blame, he should take a look in the mirror.

"I suggest to you that there can be no doubt that Colin Craig was the author of his own misfortune. It does him little credit that he somehow now blames Jordan Williams for all this."

The judge will sum up the case tomorrow, before the jury retires to consider its verdict.
