The outspoken former senator then referred to the work she'd done for groups often overlooked and unrepresented in parliament."I've worked hard to be a voice for those who don't often get much of a voice in this chamber", she began.

The ABC understands Senator Lambie has been telling her colleagues that she may have to join the seven other federal politicians who have departed Parliament House during the citizenship crisis.

Her replacement in the Senate will be determined by the High Court.

Tasmanian independent Jacqui Lambie has quit the senate after it was confirmed that she is a British dual national.

"I don't really care which side it's on, I do hope to come back".

Senator Lambie told Fairfax she sought urgent advice last week whether she holds dual citizenship.

'I found out more about his family background in recent weeks as I wrote my autobiography ahead of its publication next year, ' she said.

"He has done nothing for which to apologise and he has been my strongest supporter, my loudest cheer squad, and my closest advisor".

"It's not because of him that I am leaving this place".

Steve Martin was next on the Jacqui Lambie Network Senate ticket at the 2016 election, but there are doubts about his eligibility to sit in parliament.

She also flagged plans for a return to politics in the lower house, targeting the Labor-held seat of Braddon, where the citizenship status of sitting MP Justine Keay is now under a cloud. Her party is registering for the next Tasmanian state election and she said on Tuesday that she would have a look at the federal lower house Tasmanian seat of Braddon "should Justine Keay go down" - a reference to the citizenship question marks over the Tasmanian Labor MP.

And in case you thought otherwise, she made it clear that "you can't keep a bloody Lambie down".

"So I am going to have another swing at it and we'll see how we go this time".

"The Jacqui Lambie Network does not support the government's agenda to strip away the power of workers to stick up for themselves", she asserted, detailing the ways in which she would vote were she to remain.
