My post was from real life experience, not from a google inspired reply we voted OUT and if we have to leave on WTO rules so be it - you will see a big EU climb down as they will lose out more than us on tariffs as you put it - the way they are dictating terms shows them how pathetic they are wanting a divorce bill - we have clearly stated we will settle up on what we owe - end of and why should that come first? trade deal should have been first the latter at the end!
The UK agreed to discuss citizens rights, Ireland and the divorce settlement. The EU negotiators asked the government for their thoughts on those issues and none was forthcoming. So they asked again and yet again none was put forward. Finally, the UK government presented its' 'position papers', which bore no resemblance to the reality on the ground. The position paper on Ireland has more holes in it than Swiss cheese. Never mind Citizens rights - which the EU doesn't trust the UK to deliver considering the Home Office is sending letters out threatening to deport people. And as far as the divorce settlement - May never gave a monetary figure during her Florence speech.
If the EU had come along and said, when you leave this and that will happen and it will cost this, there would have been an almighty hullabaloo that the 'EU are dictating terms to us and not asked for our opinions'. These negotiations should have been done by Christmas. The 'no deal resort to WTO tariffs' is a sign that they have lost touch with reality. The Tories promote themselves are non tariffs free traders. It wont look good for them, in any trade negotiations with other countries, if they are seen to resort to tariffs as a threat. The EU may well 'climb down', in fact they most certainly will agree to non tariff free trade in goods. If not the UK can't use tariff money to give to for insatnce the car industry as it is against WTO rules.
But that will be against a back drop of evermore trade war tensions including EU industry with the UK's. The fallout to the financial sector is uncertain and the amount of jobs moved to the EU is still unknown, but there will be jobs moved abroad. Not good news for UK.
