Lockdown would have needed to start around 5 Feb then... right?
We would need to have completely different way of importing foods -- unaccompanied freight. And pretty much overnight.
What about stuff like petrol - can that be imported unaccompanied? Or medicines, organs for transplants...?
And nobody allowed into GB from Northern Ireland, of course.
We were operating under EU rules (transition) in Feb 2020, but freedom of movement could have been suspended... maybe fine I guess, since Brexit was happening anyway.
Hundreds of thousands of UK residents would have been stranded abroad even still now in January 2021 (this has happened to NZers & Aussies abroad).
Remember those people UK repatriated from Wuhan -- that wouldn't have happened.
Would Uk fisher-people have been able to land their catches in EU ports? I imagine no -- that would have been banned too. So sudden cessation for their industry.
Rep. Ireland would have been totally screwed, unable to use their usual land routes to get exports/imports exchanged with Europe.
