In a move that massively increased tensions within the EU and humiliated Commission President Ursula von der Leyen, Hungarian Prime Minister Viktor Orban made it clear that he would oppose a push for federalism in Europe which he believes will end democratic accountability and destroy national identities. .

Mr Orban issued a statement after Hungary’s Constitutional Court overturned the controversial European Court of Justice (ECJ) which had demanded it open its borders to immigrants from outside the EU.

Hungary’s decision to prevent illegal immigration has been one of the few blocked routes across Europe to the English Channel with thousands of illegal migrants attempting to reach the UK after crossing the EU.

Mr Orban, who is preparing for an election in April where his party could lose power to a new coalition, said EU law leads to the “disintegration of traditional communities” and the right of people to a homeland .

He continued: “At the end of the day, in terms of fundamental rights, Europeans today have no rights over their country, their language, their culture, their family and their God.

“The decision of the Hungarian Constitutional Court takes a stand against this.

“We need a disrupted human rights system and put it back on its feet.

“It is in this light that we must read what the decision says on the powers of the European Union and the sovereignty of Hungary.”

And in a direct threat to Brussels, he added: “The Hungarian state has a duty to prevent serious violations of the identity of individuals – even if such violations stem from a judgment of the Court of Justice of the United Kingdom. ‘European Union or gaps in the exercise of power.

“The traditional social environment of people living in Hungary should not be allowed to change without a democratic mandate and state control. “

The insistence that ECJ rulings should take precedence over national courts was one of the reasons British voters backed Brexit in the EU referendum.

Hungary has now joined Poland, whose constitutional court ruled in October that domestic law took precedence over EU law in October.

The Polish decision sparked a row within the EU with the European Commission and the European Parliament threatening to expel Poland from the EU or withhold funds.

Now that Hungary has joined with its fellow Eastern European in resisting attempts to create a European superstate, the prospects for a major split have increased.
