As I said start by going back to the Dublin agreement as a starting point. An arrangement that not perfect worked a hell of a lot better than the current state of affairs.
Please explain what is this ‘open border’ policy you keep banging on about, who is advocating it, how is if causing the current problem as we currently have no open border they are more closed than ever ?
If you mean something like the freedom of movement we had in the EU, why is the situation far worse since we pulled out of FOM and the Dublin agreement.
