Arnoldas Pranckevičius, the head of European Commission representation in Lithuania, made his predictions for the world if the trade bloc was to imminently disappear.
Addressing an audience in his Tedx Talks speech, he said Scotland would become independent, the migrant crisis would worsen and wars would break out in Eastern Europe.
He also predicted America would eventually become embroiled in a “big confrontation” with China before Kim Jong-un sends a missile to South Korea.
Arnoldas Pranckevičius called the EU a "very precious gift"
Who could have imagined three years ago that today we would be saying goodbye to one of the most precious members of this club – United Kingdom
Mr Pranckevičius said: “Well you would say ‘horrible, nightmare, what a dream but it’s only a dream right? It never comes true’.
“But who could have imagined three years ago that today we would be saying goodbye to one of the most precious members of this club – United Kingdom – that we’re about to start negotiations on Brexit talks.”
He then praised the single market and the need to “safeguard” the trading bloc.

The diplomat said: “If the European Union did not exist you would not have the biggest single trading bloc in the world, the biggest single market which is the main trading partner for even 80 countries in the world including Russia, China and the United States.
“If the EU did not exist you would not have the biggest development [and] aid provider in the world, which every year spends €89billion for aiding countries in Africa, in Latin America, Asia and elsewhere.”
He said an alternative to the EU would be “much worse” that the current set up.
“There's always an alternative, absolutely, but the alternative is much worse and also the alternative can be actually something we have left behind our backs,” he said.
“What is necessary indeed is, as I said, is trying to safeguard this very precious gift which was given to us by Robert Schuman and Jean Monnet 60 years ago.”
