No one owes you any explanation on how or why that voted for anything. You need to get over yourself.
How will the UK export to other countries hmm, if only there was worldwide structures and bodies to facilitate this eh?
What you see as regression is and was the defacto position from day one. It is in the EU statute (article 50) that we are still following and adhering, this isn't a UK rule or law. May did (wrongly in my view) acquiesce on a lot of what actual leavers campaigned and voted for but like Turkeys voting for Christmas remainer's were not happy, and voted any compromise down.
We will get a FTA trade deal which Barnier originally wanted or we will trade on WTO while moving any imports or exports that have onerous tariffs to new markets as we open worldwide FTA's. It is an interesting test of Free markets versus protectionism, something I am really looking forward to seeing play out.
You don't owe me any explanation, just thought that someone would come up with a credible one.
You seemed to have forgotten that Johnson signed the WA and PD but now rolling back on it which means that the last four years have been a complete waste of time and gives a hint to the rest of the world how trustworthy the UK has become.
But you're either in or out not some halfway house , you're out, now deal with reality .
You still don't seemed to have grasped that the UK have to comply with the import regulations and standards of the countries the UK would export to, whether that's the EU, the USA, China, Ghana, Australia or wherever. You can't tell them all that the UK are independent and can do what they like. Tariffs are imposed by the importing country not the exporting country which will normally be passed onto the consumer.
The type of deal you get with the EU or any other country or blocs of countries will depend on the standards the UK have. If the UK stay closely aligned to the EU then there will be a deal if they don't there won't be, it is simple as that, it's not Barnier who decides or some mysterious unknown bureaucrat , it's the 27 EU states who decide what he negotiates.
As there are only ten months left, shouldn't the UK decide whether they want- free and open trade with everybody, FTAs or WTO rules and understand what each of them implies.
