MAPPED: The countries threatening to tear European Union APART in wake of Brexit
THESE four eastern European countries are threatening to tear the EU apart following June's historic Brexit vote.
German leader Angela Merkel and Jean-Claude Juncker face a wave of Euroscepticism
Leading politicians in the Czech Republic, Hungary, Slovakia and Poland have all seized on the referendum result to heap pressure on Eurocrats.
They have been particularly critical about mounting pressure from Brussels to take in more refugees fleeing the Middle East.
Here Express.co.uk looks at the most outspoken attacks on the EU from the so-called 'Visegrad Four', or V4.
Czech Republic
Czech president Milos Zeman has called for a total ban on migrants in a desperate bid to thwart possible Islamic State (ISIS) terror attacks.
Speaking earlier this month, he said: "Our country simply cannot afford to risk terrorist attacks like what occurred in France and Germany.
"By accepting migrants we would create fertile ground for barbaric attacks."
Officials in Poland, Hungary, Slovakia and the Czech Republic have slammed the EU
Czech president Milos Zeman has linked the migrant crisis to ISIS terror attacks
And earlier this year Mr Zeman claimed it was "practically impossible" to integrate the Muslim community into European society.
He added: "Let them have their culture in their countries and not take it to Europe. Integration is possible with cultures that are similar, and the similarities may vary."
He also branded the refugee crisis an "organised invasion" and urged young men fleeing Syria and Iraq to "take up arms" against ISIS instead.
Hungarian PM Viktor Orban has called a referendum on the EU's migrant quotas
Hungary
Hungary has called a referendum over whether or not the country should accept a mandatory quota of migrants imposed by Brussels.
Prime Minister Viktor Orban has predicted the vote on October 2 will spark a "tsunami" of other referendums across the beleaguered bloc.
He said: "I expect a lot of other European countries, especially the historical V4 – the Czech Republic, Poland and Slovakia – to follow Hungary's footsteps.
"Even if they won't hold an actual referendum, I believe they will at least attack the EU mandatory quotas on every forum."
Mr Orban sparked controversy in July after branding migrants "poison", adding: "Every single migrant poses a public security and terror risk."
And Gyorgy Schopflin, an MEP from Mr Orban's party, also caused outrage after saying pigs’ heads should be impaled on border fences to deter Muslim migrants.
Robert Fico, the Slovakian leader, has taken a hardline stance against Islam
Slovakia
Slovakia's Prime Minister Robert Fico has also taken a hardline stance against migration and Islam, saying the religion has "no place" in his country.
Speaking in May, the right-winger said: "The idea of multicultural Europe has failed. The migrants cannot be integrated, it's simply impossible.
"I do not want tens of thousands of Muslims coming here and promoting their own stuff."
The future of the European Union after Brexit
Poland
In the wake of the Brexit vote, former Polish leader Jaroslaw Kaczynski warned against any attempts by the EU to punish the UK.
He said: "The initial proposals from these big countries encourage the break-up of the union.
"Britain is being treated arrogantly today, which is a hysterical reaction."
