'Fantasy' to think others will follow Brexit, EU's Moscovici tells Trump

Asked about Trump's comments in an interview with the Times of London newspaper, European Economic Affairs Commissioner Pierre Moscovici said the cost of Brexit would be "considerable" and that it would deter other countries to follow suit.

"I'm not worried, I think this idea that Brexit is going to be contagious is a fantasy, a bad fantasy," Moscovici told reporters in Paris.

"Brexit is not a great thing," he said and warned Trump that comments advocating a break-up of the European Union would not get the trans-Atlantic relationship off to the best start.

Europe's best response until Trump's inauguration would be to remain in "wait-and-see" mode and watch the first steps of its new administration.

But asked about Trump's comments on slapping tariffs on German carmakers such as BMW which sought to import cars to the U.S. from plants in Mexico, Moscovici said:

"We must be extremely vigilant, mobilized and, when the times comes, reactive, if a certain spirit is confirmed."

"Europe must not be naive and Europe must be able to react," he said.
