BUDAPEST — A member of Viktor Orban's inner circle has resigned after the Hungarian prime minister spoke out against becoming "peoples of mixed race".

Zsuzsa Hegedus, who has known the nationalist Orban for 20 years, described the speech as a "pure Nazi text", according to Hungarian media.

The International Auschwitz Committee of Holocaust survivors called the speech "stupid and dangerous".

Orban's spokesman said the media had misrepresented the comments.

The speech took place on Saturday in a region of Romania which has a large Hungarian community.

In it, Orban said European peoples should be free to mix with one another, but that mixing with non-Europeans created a "mixed-race world".

"We are willing to mix with one another, but we do not want to become peoples of mixed race," he said.

Orban's anti-migration views are well known, but for Hegedus Saturday's speech crossed a line.

"I don't know how you didn't notice that the speech you delivered is a purely Nazi diatribe worthy of Joseph Goebbels," she wrote in her resignation letter, according to the Hungarian hvg.hu news website.

Goebbels was the head of Adolf Hitler's propaganda ministry.

Hungary's largest Jewish group also condemned the speech and called for a meeting with Orban.

Responding by letter to his longstanding adviser, Orban defended his words.

"You know better than anyone that in Hungary my government follows a zero-tolerance policy on both anti-Semitism and racism," he wrote.

His spokesman, Zoltan Kovacs, said the mainstream media was "hyperventilating about a couple of tough lines about immigration and assimilation", but had stayed silent on the main points of the speech.

Orban also spoke about the war in Ukraine, arguing that the West's support of the country had failed, sanctions against Russia were not working, and that a negotiated peace deal should be the priority.

Despite receiving large amounts of EU funds, the Hungarian government led by Orban frequently clashes with the EU over rule-of-law issues such as press freedom and migration.

Hungary's prime minister has in the past been on good terms with Russia's President Vladimir Putin, and is the only EU leader to openly criticise Ukraine's President Volodymyr Zelensky. — BBC
