Yes but it seems unclear whether we can just continue or not according to the WTO itself see this article https://www.theguardian.com/busines...rexit-trade-talks-start-scratch-eu-referendum and even if we can developing the schedules is actually the work of step 2 with all the bilateral talks and step 3 is the writing and submission of them and step 4 is the members approval of them. So if the WTO accepts that we are a member, we still have to put schedules in place to cover all existing trade deals that we are involved in at present, by virtue of being an EU member. This is not just with the 27 but with every country that we have an existing deal with as an EU member. This is not the work of 2 years but of many years and of many trade negotiators just to be where we are now.
I'd gusee that North Korea would let us trade with them eith minimal red tape.
