Can't win with racists.
They wanted Brexit cos of racism, even though they knew it would take a hit economically. They didn't care.
Post Brexit/covid there was a shortage of workers, especially in certain sectors, so these visas were given to fill up these shortages, eg in health care, nurses, social care, as well as students paying rip off fees to study here in universities so locals can get it cheap. But it doesn't matter - the racists don't care.
So at the end of the day, without any leadership making the debate for responsible immigration, then you are left for the population to say YES WE WANT TO BE POORER, AND HAVE <deleted> SERVICES, but no immigration.
As the asylum seekers they make up such a tiny percentage of the legal population. Again after Brexit we cannot return them back to France.
