It seems the states can negotiate an FTA in about 18 months though it does take another 2 to 3 years to implement it. It seems to be the European union with 28 sorry 27 countries that take 7 to 10 years as each country has their own issues to resolve. So while renegotiating a deal with the EU we could complete one with USA Australia canada new Zealand etc. This is one reason I guess for leaving. The UK were seen as a nuicence by other states and didn't really sign up to how the rest of EU thinks the EU should be, except perhaps 60% of the Scots and some Corbynites. Now they will be able to get to where they want quicker without UK.
Also could someone explain why you wouldn't just use the EU rules in place for importing from WTO areas that are in use today with the EU if no other arrangement is in place. Doesn't seem to require emergency rules just a bit of common sense.
