I'm scratching my head over what point you are trying to make here.

The EU published their ideas about how the Irish border issue could be resolved.

The Irish Government explained why, in their view, it couldn't work.

The British Government have not even commented on it (to my knowledge)

Instead, they went down another route (a border in the Irish Sea) and announced at the 11th hour that they had an agreement. Before it was signed, the DUP rejected it.
Then, at the 11.5th hour, an agreement was reached which essentially was the same as staying in the single market.

That was it.

Until last week when Theresa May (after arm twisting from the hard Brexiteers) announced that we would not stay in the single market, or any similar mechanism.

So....the Irish border issue re-emerged with a vengeance.

The EU tried to sort it out, the plan was rejected, and we are not suggesting a plan to sort it out.

100% the fault of our flip-flopping Government, and not having the first idea how to sort it out.

Watch next weeks exciting instalment.
