Northern Territory politician Robyn Lambley says she is resigning from Territory Alliance "with enormous relief", leaving the party without any seats in Parliament after its drubbing in the August election.
The member for Araluen in Alice Springs confirmed she would once again sit as an independent member of Parliament, seven months after joining the party in March this year.
Ms Lambley, who was the only Territory Alliance member to win a seat at the 2020 election, said she regretted not resigning earlier from what she said was now a "struggling" outfit.
"I'm relieved, I'm happy," Ms Lambley said.
"I don't want to be in a party where there's conflict about stupid things.
"Really I think it's the end of the party."
Ms Lambley's announcement came shortly after she told breakfast radio she was still considering her membership and consulting with her constituents about it.
Territory Alliance secretary Danial Kelly said he wrote to Ms Lambley on Tuesday morning advising her that members of the party's management committee believed she should be expelled.
Mr Kelly said Ms Lambley was "not the right fit" for Territory Alliance.
"Her conduct is inconsistent with the culture and constitution of Territory Alliance," he said.
Mr Kelly said one example of this was Ms Lambley's decision not to use the party's official colours in official correspondence.
He said this breached Territory Alliance values of "mutual respect" and being a "team player".
"I changed the colour of my letterhead yesterday and that seemed to be something that they took offence to," Ms Lambley said.
Ms Lambley said she joined the party as an "experiment" after she was convinced by leader Terry Mills.
The party became a force in NT politics after a strong performance at the Johnston by-election and out-numbered the two-person Country Liberals opposition when Ms Lambley joined in March.
But it was all but wiped out at the election in August, when Mr Mills lost his own long-held Palmerston seat of Blain.
Ms Lambley said she remained a member after the election "as a courtesy" but said she told the party she wasn't committed to staying.
"It's been bizarre," Ms Lambley said.
"Since the election [the party] had to deal with me for the first time.
"I don't know these people very well at all ... they're kind of strangers to me, apart from Steve Klose who I've known for some time."
Ms Lambley was asked whether she would consider rejoining the Country Liberal Party, which she quit in 2015: "Never say never," she replied.
Mr Kelly said as far as he knew, Mr Mills was still a member of Territory Alliance.
