Thanks for that
@Touring Mars it's all getting a bit too complicated to follow, especially if you're not a native English speaker and the word "backstop" means nothing to you (other than "stopping at the back"
).
It's not a commonly used word here either - in this instance it literally means a 'fall back' default option that will automatically kick in unless something else is put in place - both sides describe it as an insurance policy.
The UK and the EU have already formally agreed to the implementation of a backstop, and this is why the EU side (Ireland in particular) are now saying that 'the UK must honour what it has already agreed to' -
but, they are omitting to mention a vital point - the UK has agreed to a backstop, but it is the nature of the backstop that is being disputed. The EU's version of the backstop - which many people in the EU appear to believe the UK has agreed to (which is categorically untrue) is unacceptable to the UK.
To be clear, the EU's backstop is that Northern Ireland alone remains in the Single Market and Customs Union, thus creating a Customs border between the rest of the UK and Northern Ireland i.e. a Customs border inside the UK. The UK's backstop is that the whole of the UK remains in the Single Market and Customs Union until a free trade deal with the EU is agreed, thus avoiding a hard border in Ireland and, crucially, avoiding a Customs border between NI and the rUK too.
In fairness, there are major problems with both solutions - the UK's stance is perfectly understandable - imposing a Customs border inside a sovereign state would be totally unprecedented, and would be tantamount to breaking up a nation state. Also, the idea of a Customs border between NI and the rUK has been
unanimously rejected by the UK parliament -
not a single MP of any party voted in favour of it. It will never happen.
But, the UK's backstop solution has an (obvious) problem - what happens after the transition period (of continued Single Market access)? In some way or another, there must be Customs checks imposed between Ireland and NI, and simply agreeing on a new free trade deal doesn't resolve that issue - neither does walking away without a deal at all. The solution, it would appear, is that until a technological solution that can be acceptable to the UK parliament is implemented, then the whole of the UK will stay in the EU.
I think the crucial point is that the UK cannot and will not ever accept the current EU position, but as long as that is the case, the UK is effectively stuck in the EU. Cynics might point out that this is the aim of the EU all along - to frustrate Brexit and keep the UK inside the Single Market by hook or by crook, but I don't see this as a tenable situation... it is more likely that frustrating Brexit in this manner will cause the UK government to collapse and be replaced with a much harder line Euroskeptic government, and then where does that leave us?
