Brexiteers always wanted to be able to control immigration, not never to have any.
Well, this is the issue, we always had full control over immigration as EU members, we could kick out “wrong ‘uns” to are hearts content within the framework of EU law. Which UK was instumental in making, but hey.
Collectivley the UK for whatever reason decided it was too expensive to keep track of immigration, so opened the doors so to speak, and then blamed it on the EU.
An now, quel suprise we still have the same problem, only compounded because we’ve pissed off a lot of ‘would be’ highly skilled EU imigrants with bullshit visa requirements, and we still have loads of (arguably unlskilled and without paperwork) desperados in boats trying to get here.
It’s a very British problem if ever I saw one.
