Pauline Hanson has quit as president of One Nation.

"It was my total decision," Ms Hanson told Melbourne radio 3AK today.

"It was my decision to hand in my resignation as national president.

"I've constantly got these court battles and challenges, and I couldn't do the job.

"The responsibility of being national president, I couldn't do it justice," she said.

Ms Hanson has resigned as leader of the party she founded.

One Nation national director Frank Hough said Ms Hanson would remain a member of the party in Queensland but had resigned from the leadership because of media pressure.

"She will remain a member of Queensland, but has resigned as leader and will no longer hold the post of president, or sit on the national executive," Mr Hough said from Perth today.

Ms Hanson faces a committal hearing on fraud charges in April arising from the registration of her party in Queensland.

She has pleaded not guilty to three charges of fraudulently registering One Nation in April 1997 and for unlawfully claiming $500,000 in electoral funding, which she has paid back with public donations.

One Nation co-founder and former party director David Ettridge is facing one count of fraud.

Ms Hanson lost a bid for a Queensland senate seat at last November's federal election.

Mr Hough said media attention about her role in the party and court cases she was facing had worn her down - and she wanted to take time out.

"Pauline has retired due to continual badgering by the media."

"It's just got on top of her really, and she just wants to take a step back for a year or so and concentrate on getting the court cases out of her hair and the press off her back."

Mr Hough said members of the party's West Australian executive were meeting today to discuss what their leader's resignation would mean for the party.

When questioned whether she was scared of the upcoming court case, Ms Hanson replied: "All I'm asking for is a fair go."

"I still presume my innocence, that I never registered the political party for my own self gain," she told Derryn Hinch on 3AK.

"I do believe it's a political witch hunt, and a lot of people don't have faith in the justice system - and I'm fighting the justice system."

Ms Hanson said she would consider spending more time working cattle on her Queensland property, but would not rule out a return to politics.

"I won't say that, that I'll never stand for parliament again, it's something that I have to assess further down the track," she said.

"The Queensland state election won't be for another two years, and of course the federal election is another three years down the track.

"And, people have seen that when it comes to federal politics, it's extremely hard for me to win a seat because the whole system has got it rorted against any individual.

"When the major political parties and the minor ones preferenced against me - even though in Queensland I actually had the highest personal vote - and yet didn't win a seat.

"The whole system is unfair, it's not democratic, and nothing will change until the people themselves want it changed."
