Lidia Thorpe’s relationship with ex-bikie should have been declared to law enforcement committee, Labor says

The Greens senator Lidia Thorpe's failure to declare a possible perceived conflict of interest in her relationship with a former bikie is "disappointing", according to the then deputy chair of parliament's law enforcement committee.

Anne Aly, now the minister for early childhood education, made the comment to Guardian Australia after the Greens leader, Adam Bandt, asked for and received Thorpe's resignation as Greens deputy leader in the Senate over the undisclosed relationship with Dean Martin in 2021.

While Labor has called on Bandt to explain why his office did not inform him, the opposition leader Peter Dutton went a step further in calling for Thorpe to resign from parliament.

Dutton told Sky News he did not think Thorpe was "fit to serve" in parliament, accusing the Greens of a "double standard" by calling for an integrity commission while their senator failed to disclose the relationship with Martin.

Martin, who has no criminal convictions, was associated with the Rebels bikie gang but stepped down as Victorian chapter president in 2018 after his brother Shane Martin - the father of AFL star Dustin Martin - was deported to New Zealand.

Thorpe was a member of the joint committee on law enforcement from February 2021 to April 2022.

In August 2021, the committee concluded a review of an amendment to reinforce the legality of the Australian Criminal Intelligence Commission's powers to conduct special operations and investigations.
