Billionaire investor George Soros has denounced a propaganda campaign waged against him by the Hungarian government.

Soros — a Hungarian by birth whose political views are in stark contrast to Budapest’s ruling Fidesz party — said Monday he had been targeted by an administration “stoking anti-Muslim sentiment and employing anti-Semitic tropes reminiscent of the 1930s.”

In a statement published on his website, Soros also rejected seven statements in a “national consultation” orchestrated by Viktor Orban’s government, which claimed he wanted to settle at least 1 million migrants a year in Europe and pay them each thousands of euros.

The Hungarian premier has often vilified Soros, whose ideals are squarely at odds with Orban’s view that European culture is under an existential threat from migration and multiculturalism. Orban has previously described Western liberalism as “spiritual suicide” for Central Europeans.

In July, the then-incumbent prime minister launched a nationwide television and billboard advertising campaign accusing Soros of devising Europe’s refugee influx. Critics of Orban’s drive to condemn the 87-year-old investor said posters were not dissimilar to the anti-Semitic imagery of the 1930s, which portrayed Jews as political manipulators.

Meanwhile, the Fidesz party sent out 8 million letters to Hungarian citizens last month, attempting to provide further detail about Soros’ alleged political agenda.

Soros responded publicly for the first time Monday and said attacks from Hungary’s government contained “lies and distortions” that were designed to create an “outside enemy.”
