"If we look at the Great Britain closely, we will see that the country is destabilized, the government cannot function properly, Scotland and Northern Ireland are considering leaving the United Kingdom, thus the referendum brought many problems without solution. I think that this will act as an example of how not to do and one should not expect a domino effect," Kappel told the broadcaster RT in an interview.
The European Union must concentrate on reforms to provide national governments with more powers, Kappel noted.
On June 23, the United Kingdom held a referendum to determine whether or not the country should leave the European Union. According to the final results, 51.9 percent of voters, or 17.4 million people, decided to support Brexit, while about 16.1 million opposed it.
