The border “solution” as I understand it is a joke: it imposes effectively two borders, and customs checks on the Irish mainland, which previously were a no-no, proposes technical solutions which don’t currently exist and which the EU would be expected to sign up to blind, and introduces the principle of rolling consent on a 4-yearly basis by the NI assembly - not actually sitting at the moment for a start and with seemingly no prospect of it doing so for the foreseeable future. The DUP like it I suspect because they think it gives them a veto, especially if the principle of bipartisan agreement in the assembly is abandoned. And because I also suspect they’d be quite happy, actually, to see a hard border return eventually.
What I have never understood here is: what is the problem with the principle of the backstop if one is confident that one won’t be needed when the time comes anyway!
We had Merkel’s 30 day challenge which of course came and went unmet with barely a word.
One is tempted to use the word: “humbug”
