Well: The effects on all the Brits??? Good question.
So far they have established an Anti Brexit Party.
Loads of the promises given to the British public have been a Haux. A lot of hot air speeches were given.
The money they thought they could save and give to the National Health System never happend.
Europe was Brittens largest Exporter. Now with new import taxes and paperwork, the trades have slow down tremendously.
The larger amount of Fish they thought they could catch and sell is rotting away, because customs procedures are too slow and they can not move the fish before it goes bad.
I have stopped buying from the UK, since import tax and procedures turn any deal into a nightmare, financially and time wise. And what I can see, I am not alone in that. Even many Brits over here in Spain have stopped buying direct from the UK
And so I could go on and on.
I am glad I no longer live in Britten, but in Spain, where 90+ % of the Brits (several hundred thousands) are Anti Brexit.
