Prime Minister Viktor Orbán said: "We will stand up and fight for Hungary's sovereignty and for the interests of the Hungarian people."
During an interview on public radio on Friday morning, PM Orbán said Brussels was "working to ensure that Hungary has a government that implements its policy... They want to redirect us, but this runs contrary to the interests of Hungary and we won't side with them."
"If this cannot be done using nice words, it will be done through a political fight," he added.
PM Orbán said European Commission President Ursula von der Leyen and Manfred Weber, the head of the European People's Party, considered Hungary "not as a partner, not even an adversary but an enemy... They have made their own decision: they want a change of government in Hungary."
