Greens Senator Sarah Hanson-Young has urged the federal government to condemn Queensland Senator Fraser Anning for attending a protest organised by ultra nationalists, the United Patriots Front.
She said Senator Anning's support for a protest promoting racist views and inciting violence shows he is "unfit to be in the Parliament".

Far-right independent senator Fraser Anning - who demanded "a final solution" to immigration in his maiden speech to the Senate last year - attended the St Kilda rally and said it was the "start of something bigger".
Senator Anning, who now sits as an independent after being booted from the Katter Australia Party following his defection from Pauline Hanson's One Nation, uploaded several videos to his Facebook page from the rally.
In the videos, Senator Anning stands with Cottrell, poses for photos and makes inflammatory remarks about migration.
