The UK prime minister, Theresa May has made a British exit (Brexit) deal with the EU but the house of commons don't like the deal. The main reason they don't like the deal is because Northern island would be treated like a separate country from the UK. They would have checks made on their products before they enter the British Island.
Let me explain the problem the EU faces. Northern Ireland and the Republic of Ireland are two separate countries. When the UK splits away from the EU, the Republic of Ireland will remain in the EU and Northern Ireland will remain part of the UK. If goods are free to move from UK to the republic of Ireland without paying a tariff then the UK could do a trade deal with a country outside the EU and send goods that are not taxed into the rest of the EU through the republic of Ireland. For example, we could remove the tariff on Oranges from Dominica and then send them to the republic of Ireland and then the Republic of Ireland could send the oranges to Germany. This would mean that Oranges are entering the EU without being taxed.
The Irish in the North and South wanted to keep a soft border because people own assets and trade on both sides of the border. I think the best way out of this is to leave without a deal and pay the tariffs, I recall that the deal involved a £39 billion exit fee. Use the exit fee to reimburse businesses that are taxed for their exports. Isn't that a more straight forward way to solve the problem.
My son is due to be born and like his father is spending his time as a fetus in a country that is consumed by chaos and uncertainty. For me it was the Falklands war, for him it is Brexit.
