Earlier this week, the DUP set out 7 tests for any new arrangements on the NI Protocol. But does any model work, especially if you throw in the UK & EU's red lines?

The key point is, perhaps obviously, to point out that there is no option that can both satisfy all the DUP's tests and be acceptable to the EU and London, even before we get to anyone else in Northern Ireland

Which suggests that as long as everyone's policy preferences remain as they are, there is not going to be a stable equilibrium and tensions are only going to continue

Something to consider as we await the UK govt's plans this week, which at best will restate previous aspirations, and at worst will further destabilise the situation
