If the UK leaves the customs union, as repeatedly promised by TM, then there has to be a customs border between the UK and the EU.Little John wrote:What Irish border problem? Spell it out please UE.
Ireland is in the EU. Northern Ireland is in the UK. So by default, there will have to be a customs border between NI and the republic.
Any sort of customs border between NI and the republic is deemed politically unacceptable on both sides of that potential border, and by the EU.
The EU's demand regarding the sequencing of talks, which supposedly is there to ensure there will be no hard border in Ireland, is actually guaranteeing that very outcome. As things stand, if the talks fail then the UK crashes out of the EU with no deal, which would mean a hard border is needed in Ireland. The EU has demanded that before it is willing to talk about anything else, including the UK's future trading relationship with the EU, that the UK agrees to a "backstop" arrangement, which basically means that if talks fail then the UK has agreed to either an internal border within the UK (which the DUP will block, and is about to become illegal anyway) or that the whole of the UK remains in the customs union without specifying a price from the EU.
There's no way the UK can agree to this. At the moment, the default outcome is a messy, bad-tempered no-deal brexit. The EU is demanding that in order to avoid this outcome, the UK must agree that the default outcome is a messy, bad-tempered no-deal brexit, except with some added features which make is even worse than that. The UK would have to be stark raving mad to agree to this.
