Independent Tasmanian Senator Jacqui Lambie will resign from Parliament on Tuesday after confirming she holds dual citizenship.

Senator Lambie confirmed she is a UK citizen by descent thanks to her Scottish-born father while speaking on Tasmanian radio station LAFM Tuesday morning

The resignation comes a week after she expressed confidence there was no issue with her citizenship.

“I didn’t think I actually had a problem with it, so I never gave it a second thought,” she told LAFM.

The outspoken senator said after discussions with her father, she realised she had breached the rules, telling LAFM she called her father early Thursday morning and said: “Dad I’m gone aren’t I?”

Senator Lambie will make a statement to parliament tendering her resignation at about 12.40pm AEST.

She said she will re-contest her seat at the next election.

“I won’t be laying down. I’m going to get right back on,” Senator Lambie said.

“So I am going to have another swing at it and we’ll see how we go this time.”

Unlike other dual citizens who have failed their constitutional requirements under Section 44 of the Constitution, Senator Lambie may not be replaced by those beneath her on her 2016 election ticket.

Devonport mayor Steve Martin is next in line to take Ms Lambie’s seat in the Upper House, but Professor George Williams of the University of NSW told AAP his succession could be in doubt because of Mr Martin’s role in local government.

According to the constitutional expert, the High Court would need to decide if a local council position is an “office of profit under the Crown”.

“If I am a dual citizen I will resign. If it is black and white there is no need to take it to the High Court, as simple as that,” Senator Lambie told The Mercury newspaper.

The next person on the ticket, Rob Waterman, is CEO of Rural Health Tasmania.

Rural Health Tasmania’s annual report for 2017 said it received funding from several federal government programs run by the departments of health and social services.

Senator Lambie will be the eighth parliamentarian forced out of Parliament due to dual citizenship.

The colourful senator entered parliament after the 2013 election representing Clive Palmer’s now defunct party, before quitting to sit as an independent the following year.

Senator Lambie championed a number of causes during her time in Parliament and caught the public’s attention in 2015 when she spoke publicly about her inability to help her 21-year-old son recover from his addiction to the drug ice.

More recently she launched a blistering attack on the Turnbull government and One Nation over media reform, labelling them a “disgusting bunch of individuals” for “going after” the ABC and SBS.

In May, she asserted that all politicians should be drug-tested the minute they walk through the doors of Parliament, saying people that believe the corridors of power are drug-free “are kidding themselves”.
