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.
