European Union (EU) president Jean-Claude Juncker announced that the United Kingdom will dealt with as a “third country after Brexit, and the separation would be disastrous for Britain that it will discourage other member countries from leaving the EU.

Moreover, the Union president claimed that French presidential candidate Marine Le Pen will never achieve the presidency of her country and described the EU’s relationship with U.S. President Donald Trump is “something akin to estrangement,” in a comprehensive and antagonistic interview with Bild am Sonntag.

“They [the rest of EU member states] will all see from the U.K.’s example that leaving the EU is a bad idea,” he told the German newspaper.

On questions regarding Brexit consultations, Juncker said that everything has been “prepared down to the last detail.” He also warned Britain “to prepare itself to be treated as a third country.  There will be no half-membership or cherry picking. In Europe, the choice is to eat what’s on the table or not come to the table at all.”

About Marine Le Pen, he said: “The European Union will survive Marine Le Pen because she won’t become President.”

He further claimed: “And even if she did, it would not be the end of the European project. But it would certainly rock the boat. So I hope that pro-European forces will win in France.”

Referring to President Trump’s urging of EU member states to imitate Britain’s decision to detach itself from the Union; Juncker explained the relationship with the Trump administration as “something akin to estrangement.”

He stated: “The fact that the American president welcomes the U.K.’s decision to leave the EU and is encouraging other countries to follow suit is an unprecedented phenomenon. We need to engage in intensive dialogue.”

After the Dutch elections, he urged the citizens of EU to oppose the upsurge of populism in Europe.

“If they just sit back in their armchairs while the populists march on, the latter will always be one step ahead,” Juncker warned.
