Great Britain is great again!!!
Now the Eastern Europeans, including me, will go back to their country of origin.Then the Indians, Pakistanis and Bangladeshis.Then the Caribbean immigrants. Boris Johnson best sends back all the jews to be fair. The Italians have to go. No more ice cream. But that’s fine. Actually, the French, Dutch and Germans too. These Huguenots and Normans have been nothing but trouble. Best send back the Nordics from north east England. They messed up the true British bloodline. And who needs barm cakes anyway? In the south, having kicked out all the Germans has already dealt with those pesky Angles and Saxons, and of course losing the Italians means the Romans have gone. Those groups will have taken their peculiar immigrant religion worshipping a crucified middle eastern mystic, so that cleans things up a bit. The Celts came over a few years before the Romans. But none the less they did immigrate. Get rid of them. No more ginger! That’s a bonus I suppose.
So what are the Brits left with? The bones of a few hundred beaker people and the tattered remains of their log boats. Send them back! Britain is full.
As for those hunterer gatherers, walking over from Belgium - who needs Belgians?
If Brits send back all the immigrant communities the UK would be just fine, because there would be no one here.
