Nor me but It depends Roydo, each country/company can do trade deals with another country/company without the EU. The EU negotiate country to country free trade deals. We may well have to make a new agreement with a particular country and that is also true of the EU who may also have to do the same because the U.K. (being such a large market) is no longer part of the deal. Many of these deals may just require tweaks (change EU for U.K.) and even larger more complicated deals can be sorted out by the lawyers quickly if there is willing from both sides, and in very many instances this will be the case. The problems for both the U.K. and EU will be in instances where the current 3rd country, such as New Zealand or Australia will insist that the EU still takes the same amount of product even though the U.K. was their main destination. It’s a ball ache, but everything can be resolved unless someone doesn’t wish it to be. The same will happen with the WTO where one or two countries may think they are able to blackmail or renegotiate tariffs, quantities etc etc, but unless the major economies want all trade to come to a stop, a way through will be found.
In respect of product certification, they will carry EU certification standards, which we will just adopt, and British standards, all of which are currently agreed and understood between trading nations and the trading importing companies. All this talk of job loss etc is smoke and mirrors, this is a massive job creation exercise......
