We leave with no deal, regardless, as you cannot negotiate a trade deal while still a member state of the EU. All Mrs May had was a deal to talk about a future deal! It also meant paying a shitload of money to the EU -£36 billion, while still following all their rules during a transitional period when things would remain roughly the same, their laws triumphing the UK's, us having to beg them for trade deal - unlikely as they already had our money, which is all they really want, and a made up problem called the Irish backstop, the escape from which would be controlled by the EU. Therefore we would never leave.
The EU has a eastern border too with non EU countries like Albania and Macedonia-there is no talk of an Albanian backstop, trade flows through the border with technology checks and some border checks, as it should be. The EU also had given membership status to some French dependencies and many of those border African countries which are unlikely to have the same trading standards as the EU, yet trade flows through those borders too. However, it seems the EU just has a problem with the N Ireland/Irish border even though the UK has always followed the rules and regulations and have the same standards as the EU already- as I said, a made up problem.
No deal simply means trading under World Trade tariffs which the majority of the countries of the world do anyway- shock, horror, it actually works. No cliff edge, no crashing anywhere, just stepping into freedom and that is priceless. Although there may be some casualties and disruption for a short time ( caused by the EU), most people won't notice the difference at first. Some things may cost more, others less. Prices went up significantly when we joined the Common Market in 1973 but no one said we 'crashed in'!
Buy British, wherever you can, to support our farmers and businesses. When companies like VW, French wineries and the like see the tariffs go on and people buying cheaper alternatives, they will soon put pressure on their governments to negotiate a deal with us. Liam Fox has already agreed to carry over many free trading arrangements with countries which already had one with the EU, like Switzerland, Israel and Korea. Yes, the EU would rather give a free trade deal to Korea before it sees the UK being successful as an independent country! Meanwhile suspicious packages have been found in the UK and the finger is being pointed at the IRA. As they say, with friends like these, who needs enemies!
