It does not have to be like this

(I had intended my thoughts to be one post but it would be far too long so I have split it up into more than one.)

I am a Leave voter - I voted Leave and would vote Leave again. I voted Leave because I wanted to be out of the jurisdiction of the European Court of Justice (ECJ) and of the unelected Commission; so that MP's were answerable not to the Commission but to their electors in their constituencies, to the United Kingdom voter.

Mrs 'President' May said the following in her Lancaster House speech:

That starts with our close friends and neighbours in Europe. So as a priority, we will pursue a bold and ambitious free trade agreement with the European Union.
This agreement should allow for the freest possible trade in goods and services between Britain and the EU’s member states. It should give British companies the maximum freedom to trade with and operate within European markets – and let European businesses do the same in Britain.
But I want to be clear. What I am proposing cannot mean membership of the single market.
European leaders have said many times that membership means accepting the ‘4 freedoms’ of goods, capital, services and people. And being out of the EU but a member of the single market would mean complying with the EU’s rules and regulations that implement those freedoms, without having a vote on what those rules and regulations are. It would mean accepting a role for the European Court of Justice that would see it still having direct legal authority in our country.

The United Kingdom was therefore going to leave the Customs Union and "So we do not seek membership of the single market. Instead we seek the greatest possible access to it through a new, comprehensive, bold and ambitious free trade agreement."

On the 29th March 2017, May then gave formal notice that the United Kingdom was invoking Article 50 of the Lisbon Treaty. From what I have read it seems the Article 50 notification cannot be revoked. In response Donald Tusk wrote:

..While an agreement on a future relationship between the Union and the United Kingdom as such can only be concluded once the United Kingdom has become a third country  http://news.bbc.co.uk/1/shared/bsp/hi/pdfs/31_03_17_eu_draft_guidelines.pdf

The reason given for leaving the single market was thus so that the United Kingdom would not be subject to the 'Four Freedoms' especially Freedom of Movement of people.

On 29th March 2019 the United Kingdom will become a third country i.e. NOT a member of the European Union and only at that point can a new agreement be concluded - AFTER we have left. So what does third country ACTUALLY mean?

It means basically that access to shared databases will probably stop in the 'No Deal' scenario. Access to the Single EUROPEAN sky, medicines, agriculture, customs and other databases may well be switched off. Not because the European Union is vindictive but because the United Kingdom is taking the Sovereign decision to leave the European Union. It is a United Kingdom decision not an EU one.

Michael O'Leary of Ryanair, of whom I am no great fan, has already warned that No Deal will mean that flights to the European Mainland will cease and has stated that Ryanair flights might stop as early as September 2018.

Between 29th March 2019 and the agreement of a 'new, comprehensive, bold and ambitious free trade agreement' the United Kingdom will be in a 'limbo' until it appears on the official 3rd Country list maybe six months after 29th March 2019.

Then the United Kingdom will be officially a third country with all that implies - which will be the subject of Part Two. 

It really doesn't have to be like this.
