Pauline Hanson's sister could join her in Australian parliament

SYDNEY, AUSTRALIA - MARCH 29:  Former One Nation Party leader Pauline Hanson with her sister Judy Smith attend the Sydney launch of her autobiography "Untamed & Unashamed" at Dymocks on March 29, 2007 in Sydney, Australia. In 2003, Pauline Hanson was sentenced to three years' jail on convictions of fraud, of which she served three months before the verdict was overturned and she was released with a full withdrawal of the charges. Her memoirs tell the story of how she came to be charged, her fight to prove her innocence and of her life before and after politics.  (Photo by Patrick Riviere/Getty Images)

The sister of controversial Australian politician Pauline Hanson could be set to join her in parliament.

Ms Hanson is the founder of One Nation, a nationalist right-wing party, and has often made the headlines for her provocative statements.

Her sister Judy Smith could be set to replace Queensland One Nation senator Malcolm Roberts if it's deemed that he is ineligible to de elected due to dual citizenship. He revealed this week that he held dual citizenship with Britain when he was elected, as the dual citizenship problem continues to shake up Australian politics.

Ms Smith has described herself as one of Ms Hanson's biggest supporters and is a likely candidate to replace Mr Roberts, the Herald Sun reports

In recent weeks, two Greens politicians resigned from Parliament after it was revealed they held dual citizenship. Liberal national MP Matt Canavan is also being questioned about his citizenship, as he holds dual citizenship with Italy but claims that he did not consent to arranging the citizenship.
