Donald Trump predicts European Union demise

US presidential candidate Donald Trump has used his crystal ball to predict the break up of the European Union, in an interview with The Times.

Britain voted to leave the bloc during a referendum held last Thursday with a majority of 52% voting for a Brexit.

Trump was on a visit to Scotland hours after Britain opted to leave the European alliance, and said that due to loose migration, the area could be "unrecognisable" within a decade.

“The people have spoken. I think the EU is going to break up," Trump said. "I think the EU might break up before anybody thinks in terms of Scotland. I really think that without the immigration issue [the EU] wouldn’t have had a chance of breaking up ... the people are fed up, whether it’s here or in other countries. You watch: other countries will follow.”

Immigration has been a key battleground for the presumptive Republican nominee for the Whitehouse, as he suggested to build a wall on the American border with Mexico.

Trump said that caution should be a key word for the United Kingdom

When he was asked how he would deal with Europe's migrant issue in southern Europe, he said he wouldn't allow them to enter.

"I would help them but I would have to bring them back and maybe create safe zones over there in some form."

“You’re going to have to. You cannot allow this to happen to Europe. It would be so much easier for me to tell you: ‘Oh, I’d accept them with open arms,’ but Europe is not going to be recognisable in 10 years.”

Trump said that caution should be a key word for the United Kingdom now, particularly in the case of Scotland as the home nations have to stick together to protect their interests.

“One thing I have to say about Scotland is they have to be careful. The oil price is down and those [Scottish revenue] numbers are a lot different when the oil prices are down.”
