Shall we not talk about what might be and the halcyon days of the 1970s? We no longer live in the 1970s, flared trousers are a no no, Noel Edmonds isn't on Radio 1 and deep fried avocado isn't something the "in crowd" eat anymore?
On Thursday the UK will start to issue their Technical Notices, which will be the first part of preparing society for a D1ND scenario. At that point we will all get to see what Government thinking is. I've no inkling as to what they say.
However, I can share this...
https://ec.europa.eu/info/brexit/brexit-preparedness/preparedness-notices_en These are the Technical Notices from the EU, explaining how the EU is going to handle a D1ND Brexit. This is how the EU WILL handle the UK if a Transitional Period or a Withdrawl Agreement is not in place.
You can find the information on international trade at the end of the page, under the heading TAXUD. (these are the only ones relevant to the trade discussion)
The one you need to look at is "Preferential rules of origin" - essentially this is techtalk for "Trade Deals". The fourth paragraph makes thing clear... the trade deals wont apply to the UK. To get back to your post, we have 57 different trade deals, including with trading blocs in Central / South America and Africa. (
http://ec.europa.eu/trade/policy/countries-and-regions/ is an index page to those deals) People need to understand that it not just goods moving between the UK and EU that are effected. So, food imported from those countries which is currently duty free, but post Brexit will not be as we wont be party to the Trade Deals. Of course the UK has three options.
1. remove tariffs and make everything duty free. We can do this, but we would have to make goods duty free from everywhere - otherwise you contravene WCO rules on favoured nation - and of course we wouldn't get the tax stream from import duty.
2. roll over trade deals. This is HMG's favoured option. However, this is extremely difficult because it means changing all the Rules of Origin (I've explained before how a car made in Sunderland isn't British).
3. Charge duty on what were previously duty free goods and put the price of food up in the process.
Later on in Section 3 it talks about removing UK goods from the rules of origin. This will have a direct effect on UK exporters as their goods may then remove certain products out of trade deals as the Rules of Origin would have changed
The other important document is the one headed "Customs and indirect taxation". This pretty much sets out how the EU will trade with the UK in the future, and its not pretty reading.
Sorry, this is all really technical. Possibly accepting I am in a no win situation and am now likely to be accused of elitism or patronising - if anyone wants any of what is in the EU documents explaining, I'll be happy to do so.
