An Australian senator has been suspended for a week after wearing a burka in parliament to push for a ban on the Muslim garment.

Pauline Hanson was condemned by fellow senators – and later formally censured – for the stunt on Monday, with one colleague accusing her of “blatant racism”.

The Queensland senator, of the anti-immigration One Nation party, was seeking to introduce a bill that would outlaw full face coverings in public – a policy she has long campaigned for.

It is the second time she has worn the garment – which covers the face and body – in parliament, and said her actions were in protest at the senate rejecting her bill.

Shortly after other lawmakers blocked her from introducing the bill on Monday, she returned wearing a black burka.

“This is a racist senator, displaying blatant racism,” said Mehreen Faruqi, a Muslim Greens senator whom the Federal Court last year found was a victim of racial discrimination by Hanson – a judgement the latter is currently appealing.

Fatima Payman, an independent senator from the state of Western Australia, called the stunt “disgraceful”.

Foreign Minister Penny Wong, who serves as leader of the government in the senate, on Tuesday moved a motion to censure Hanson, claiming she “has been parading prejudice as protest for decades”.

The motion, which passed 55 votes to five, states that Hanson’s actions were “intended to vilify and mock people on the basis of their religion” and were “disrespectful to Muslim Australians”.

Wong earlier argued Hanson was “not worthy of a member of the Australian senate”.

In a post on Facebook, Hanson wrote: “If they don’t want me wearing it – ban the burka.”
