Palmer United Party senator-elect Jacqui Lambie says she's prepared to become a ''political prisoner'' if she's found to have breached Tasmania's electoral act.

Ms Lambie's name appears authorising a PUP newspaper advertisement for the state election that is being investigated by Tasmania's electoral commissioner.

She says she did not see the ad before it was published in Hobart newspaper The Mercury but is prepared for the consequences, which could include her not being allowed to take up her Senate seat in July.
