The sole Member State to withdraw from the EU

Since 1957 Twenty-two European Countries have joined the founding six member States (Germany, France, Italy, Netherlands, Belgium and Luxembourg) to become member States of the European Union. The International Organization of European countries was formed in the aftermath of World War II to reduce barriers and increase cooperation among its member States.

Unfortunately, the UK is the sole member State to withdraw from the Union. After the UK's government had triggered the Article 50 of the 2007 Lisbon Treaty, most member States of the EU were afraid Britain would try to retain all the benefits of European Union membership without obligation.

The EU single market covers all members States and four other countries, such as Iceland, Switzerland, Liechtenstein and Norway. It allows people, goods, services and money to move freely as within a single country while also striking trade deal with non-EU countries. Norway, which as above mentioned is not member of the EU, has a high level of access to the single market and almost the same level of tariffs and trade barriers with EU countires. On the other hand, Norway accepts a relevant amount of EU regulations and directives, that includes the "four freedoms", the free movement of people, goods, services and money.

Since June 2016 many experts have pointed out the negative impact that  a  no-deal Brexit could have on the UK in terms of "Shock of supply" of goods. In the case of no-deal scenario the EU is obliged under WTO to impose tariffs on goods which will be imported from the EU. Obviously, consumers and businesses in England, Scotland, Wales and Northern Ireland would have to pay more for good and service, as customs duties would be paid for goods going to and coming from the European single market. Therefore, the UK will not be an attractive place to do business.
According to the World Economic Forum, some car makers in the EU have already said any British customer buying car made in the EU will be charged  ten per cent extra, because  that would be effect of increased custom tariffs in the case of no-deal Brexit. In this perspective, British car makers, who are the UK's biggest exporters, have warned that the UK's departure from the European Union poses the “biggest threat in a generation”. With regard to Scotland, three out of four its international trading markets are in the EU (France, Germany, Netherlands, and USA). With food and drink exports reaching over £ 5 Billions, Scotland products are in demand in the world over.  

To summarize, Britain is unprepaired to leaving the EU with no-deal, considering the disruption to British economic relations with UK's neighbours.
