Will Ireland Benefit The Most From Brexit? Watch
The UK will be piggy backing off Ireland just to get the "benefits", from the EU. The EU will use Ireland as a back door to work, trade, etc, with/in the UK.
Ireland on the other hand has an economy that relies far more on the UK than the rest of EU therefore it will be in their interest to avoid a no-deal Brexit. Doubt there would be much that can be done for the UK to harness Ireland economically as the EU would most likely see it as a back door or loophole to access the single market and I suppose it is rightly so that they would quickly close it.
