Trade with EU countries
In a no-deal Brexit, UK businesses trading with EU countries will need to follow processes they currently use when trading with non-EU countries that have no existing trade agreement in place.
Trade with non-EU countries
UK businesses may be affected by a no-deal Brexit even if they do not trade with the EU. This is because any trading agreements between the EU and non-EU countries will no longer apply to UK businesses after a no-deal Brexit.
Therefore the UK is seeking to replicate trading arrangements between EU and non-EU countries.
