In Australia, political leaders across the spectrum – from the Greens to One Nation – have united to condemn an “appalling” speech by Senator Fraser Anning in which he called for a “final solution” on immigration in Australia.

The Katter’s Australian Party senator, who defected from One Nation, also used his maiden speech to urge a ban on Muslim migration and a return to the discriminatory White Australia Policy.

Prime Minister Malcolm Turnbull described Senator Anning’s remarks as “appalling” and said there was “no place in Australia for racism”.

Energy and Environment Minister Josh Frydenberg, who is Jewish, said the comments were “ignorant and insensitive … they were hurtful and divisive”.

“I call on Fraser Anning not only to apologise but also to go and visit a Holocaust museum and to hear first hand from the survivors how the pain is still raw,” he told Sky News on Wednesday.

But the most interesting reaction was that of One Nation leader Pauline Hanson – whose infamous maiden speech in 1996 was dubbed racist for warning the country was in danger of being “swamped by Asians” – and also joined the widespread condemnation of Senator Anning on Wednesday, saying she was “appalled” by the speech.

She claimed it was written by a sacked staffer to Malcolm Roberts – the former One Nation senator replaced by Senator Anning – and was “straight from the Goebbels handbook for the Nazi Germany”.

“We are a multi-racial society and I have always advocated you do not have to be white to be Australian,” Senator Hanson said.
