Yes you did warn us Eddie (along with many other things, most of which seem unlikely to happen). I didn’t “shout you down” but explained calmly why it was unlikely in the extreme to happen. My view hasn’t changed because a couple of politicians have cast the idea about as a vote catcher.
Your notion that, should the border be restored to the UK, that illegal migrants have the right to travel to, say, Dover, is false. They have no such right. Carriers (airlines and ferry companies) have an obligation to ensure that those they intend to carry have the correct papers before embarkation. The responsibility to return illegals to their port of origin rests with the carrier. There is no way that ferry companies are going to allow huge numbers of migrants to board their ships only to see them refused permission to land in the UK. Furthermore, moving the border (as will the accompanying idea of allowing asylum seekers making a claim to settle in the UK from France) will simply attract even more migrants to the French Channel ports. In a word, it ain’t gonna happen and that is no less true today than it was yesterday before the candidates made their pitch.
This is a French problem, created by the French who allowed vast numbers of illegal immigrants to cross their borders and camp in Calais and elsewhere. It is not a UK problem and the UK has no responsibility to tackle it.
You need to think it through, Eddie, instead of being alarmed by political posturing.
