Can it be saved?
Here's my plan:
>Establish martial law
>Every person of a foreign background from a chosen list of specific countries (you know which ones) has 90 days to leave. They won't be forced to leave if they are married to a native ethnic british person or have at least one ethnic british parent. Illegals will be instantly arrested and deported if found.
>After those 90 days the whole country will be surveilled for another 90 days in search of every remaining foreigner that didn't leave the country. They will be arrested and instantly deported + have their nationality revoked. Some of the inmigrants in prisons will be deported too, their nationality revoked if they had one and forbidden from ever entering the country again
>Once those 90 days end some of the deported may request to be let into the country again. Each case will be thoroughly studied and only some like highly skilled workers may be let back into the country
