Despite the mainland of the U.K. being an island with no land borders to any other country, people have been coming here unofficially ever since humans have existed in (what is now called) Europe. People have been coming (and going) from the islands that make up the British Isles for thousands of years. Sometimes in very large numbers, often as a small trickle
Obviously one method used to get here is by ship or boat. Unofficial arrivals via small boat are obviously often in the news, but it’s not something particularly new to this country.
And despite all the bluster from the politicians, a couple of years ago, a Channel 4 documentary demonstrated that it’s even easier (with the aid of helpful people) to enter ‘illegally’ via the normal ferry routes.
If you think our so called borders are well protected, you must live in Cloud Cuckoo Land.
Border control is obviously something that the U.K. government is supposed to have full control over. But they either don’t want to, don’t want to spend the money to do it properly, or they don’t really care.
Let’s take the argument a bit further, if Scotland or Wales, or say an English region decided to separate from the U.K. and put a border in place, with their own immigration policy, would that be okay or be wrong? What about if all U.K. regions did the same? We could have hundreds of administrations each issuing their own passports in the former U.K., each with a different set of visa requirements. Then we can control the awful free movement of people within the U.K. Surely that’s just a logical extension of the principles of brexit? To move so called decision making and sovereignty to a local level? Why should Cornwall/Scotland/Wales or any other region have laws imposed by a remote Westminster parliament? Why should well off people from elsewhere come and buy so many second homes in Cornwall and parts of South Wales which forces the local young people to move away from their families? And which creates ghost towns in winter, where local businesses struggle to survive.
It’s not like the system of democracy we have is particularly good. It’s rare for a government to have received a majority of the vote in a national election. The House of Lords is appointed not elected. The privy council is appointed not elected. The head of state is not elected. The government via Parliament can override all other parts of government if it wants.
IMHO, far too many politicians and some media organisations (mainly so called newspapers) have used ANYTHING to deflect away from the failings of our own governments. So have used the E.U. as a scapegoat.
