On May 7th the result of the French Presidential elections showed that we will not see the "Frexit" in the next years. America's plan is aimed at breaking the EU into smaller pieces, and it didn't work in France. And since June 2016 most people in Scotland and Northern Ireland, who voted to remain in the EU, have been valuating the bill which has to be paid for exiting the EU.
According to the terms of the negotiations, which were framed by the EU in a paper published on March 29th, Britain must pay price for leaving the EU. It would amount to about US $ 60 billion, including negotiation costs, such as the hire of facilities for the talks, meals and other subsistence allowances.
It's easy to see why Scotland and Northern Ireland are trying to become two independent states of the EU in their own right.
