We will trade with the EU with a trade deal not a political union big difference that's what Brexit was reiterating just a trading block we will be equal partners!
Trade laws will still apply.
For example. The UK government will be unable to simply rip up the Data Protection Act , with implements an EU Directive.
If it wants to continue to supply services to EU consumers.
That means Data Protection Commissioners and controllers are going nowhere.
Again, if food manufacturer is producing food for sale on the continent. It will need to comply with EU food law.
That means only ingredients and additives on the EU list. Approved for use.
Etc.
I could go on. But you're simply talking rubbish.
