Colin Craig holds up a booklet alongside his wife Helen that outlines an alleged campaign against him.

Former Conservative Party leader Colin Craig has been outed as a foul-mouthed "Mr X" who posed as a party whistleblower.

The anonymous "whistleblower" features in a booklet distributed to mailboxes in July, in which Craig claims he was the victim of a political conspiracy.

Craig has now admitted he was Mr X, who was quoted in the booklet as describing Craig as "freakish under pressure" and said he had a chance of a comeback.

"A lot of expletives have been deleted from this dialogue," the interview begins.

Craig said he didn't see any problems with talking about himself in the third person and framing it as an anonymous whistleblower.

It was a common literary tool to get a message out to readers, he said.

"It makes for a more interesting read ... I stand by the brochure."

Craig stepped down as party leader in June after it was alleged he sexually harassed his former press secretary Rachel MacGregor.

The former leader has denied the allegations, but admitted there had been "inappropriate behaviour".

Craig has also accused Whaleoil blogger Cameron Slater of being part of a "dirty politics brigade" running a campaign to destroy his reputation.

A legal stoush between the pair was currently before the courts.

Craig was suing Slater for defamation. In a counter-claim, Craig faces defamation proceedings over the pamphlet which names Slater.

When asked about the Mr X interview, Slater said Craig was playing his own dirty politics.

"It raises serious questions about his credibility. This is a man who professes to be an honest politician who will hold people to account."

Slater disputed Craig's claim it was a common practice to use fake interviews in publications.

The Conservative Party, which collapsed after Craig was forced to stand-down, was currently trying to rebuild its board.

Party members planned to elect a new board at its annual general meeting on Saturday.

Craig said he did not plan to attend the meeting because he didn't want conflict with fellow Conservative Party member John Stringer.

However, Craig said he was still an avid supporter of the party and would not rule out a return to leadership if elected to do so by a new board.

"I'm happy to serve the party in any capacity."

Interview with Mr X, as published in the booklet:

Interviewer: Colin Craig is not in office

Mr X: Well no but he nearly ... got there last time. He gets votes and the media love him so that qualifies him to be a target.

Interviewer: Craig says he has been getting pretty positive feedback from supporters.

Mr X: Yeah well maybe he says that but ... don't forget they are mostly a bunch of bigots, they will dump him, just wait and see. Most media have already written him and the party off."

Interviewer: So there is no way back for Craig after this?

Mr X: No chance ... well OK there is a chance but only because he is freakish under pressure and he seems to be largely unphased (sic) by this whole thing."
