Disgraced former Country Liberals minister Nathan Barrett has told Parliament he will resign from the party on Tuesday following a sex scandal.

Mr Barrett announced to the Northern Territory Parliament that "certain media" and Labor's candidate for Mr Barrett's seat of Blain, Damian Hale, had set out to use his private life to publicly humiliate and destroy him.

Mr Barrett stood down from his roles in the ministry as Northern Territory sports minister and assistant treasurer on June 11, after it emerged he sent videos of himself engaged in a sex act to a woman.

He has maintained that his relationship with the woman was consensual.

"Politics is a dirty game and I firmly believe that my political enemies could not fault me in my work in the community, and so in order to bring me down resorted to this base attack," Mr Barrett said.

"Having said that I have stood down from the ministry, announced I will not run again, and now I will resign from the party tomorrow because I believe in what they do and I'm aware that my private failings should not impact their public work any further."

Upon announcing his intention to resign from the party, Mr Barrett also tabled a number of text messages as he sought to relay his version of events around the extra-marital affair, and how the issue came to be in the media.

On tabling a message that he claimed was sent to a CLP member by the Speaker of the House, Kezia Purick, Mr Barrett told Parliament: "On the 10th of June 10:53am a Member of Parliament canvasses a CLP member and not only suggests that I've sent inappropriate messages to women, plural, but asks if I had approached her in a similar way."

It was unclear how Mr Barrett came to be in possession of the text message. The message allegedly sent by Ms Purick read:

"Kezia here. A serious matter and a request to you. I have been told by a reliable person that Nathan Barrett has sent you very inappropriate text messages and I am sad to tell you that if this is true, you are not alone, he has done so to other women. If this is true and correct, would you be willing to talk to some one about it and who is trustworthy? If it is not true than [sic] I apologise for troubling you. However, Mr Barrett is in a bit of strife and I am concerned that he is using his position to exploit women. My work number is xxxxxxxx."

Mr Barrett had already announced he would not recontest his seat of Blain in the August election, but had been defiant over remaining a member of the party.

The scandal turned into a political saga when the CLP publicly questioned the motives of the woman who sent the lewd videos to the NT News.

It was later argued by Chief Minister Adam Giles that Mr Barrett had been a victim of "revenge porn" after a consensual, extra-marital affair soured.

Mr Barrett's wife was vocal in her public support for her husband in the wake of the scandal.

Prior to the scandal, Mr Barrett had been touted as a "rising star" within the CLP.
