Balázs Hidvéghi, the parliamentary state secretary of the Prime Minister's Cabinet Office, said on Tuesday that the stakes of the ongoing referendum on Ukraine’s European Union accession are "huge", arguing that Brussels wanted to decide on fast-tracking the neighboring country’s integration without seeking the public’s opinion.

"This would have catastrophic consequences for Hungary," Hidvéghi said in a video on Facebook.

He said that supporting Ukraine has so far cost Hungarian families close to 2.5 million forints each (EUR 6,200), adding that Ukraine’s accession could cost each Hungarian household an additional 4 million forints a year.

Hungarian farmers would lose 7 billion euros in EU funding, Hidvéghi said, warning that "those who say ’yes’ to Ukraine will say ’no’ to monies Hungary is entitled to."
