Prime minister Tony Abbott has compared opposition leader Bill Shorten to Nazi propaganda minister Joseph Goebbels in Question Time on Thursday. But Mr Abbott immediately threw up his hands and withdrew the comment.
It was the second Nazi Germany insult Mr Abbott has used in parliament in less than a month after he said Labor's economic policies led to a "holocaust of jobs" in the defence industry.
"The Dr Goebbels of economic policy!" the PM cried, before throwing up his hands and telling the speaker, "I withdraw! I withdraw! I withdraw, Madam Speaker!"
In response to the sledge, Labor was in an uproar leading to speaker Bronwyn Bishop throwing out senior MP Mark Dreyfus.
Fellow Jewish MP Michael Danby reportedly walked out of parliament in disgust.
Dr Joseph Goebbels was the propaganda minister under Adolf Hitler and was responsible for many of the anti-semitic speeches and patriotic films that were used by the Nazi regime.
