We can all change our mind or adjust our position during a negotiation - if that is what Barnier has done - it's called negotiation I thought
You just can’t admit the EU are ever wrong. You blame the UK for every little thing yet when it’s the UK that shifts it’s position to accommodate an EU position, and the EU moves the goal posts they’re just changing their mind. How bloody unprofessional!
I’ll make it simple for you. When you declare a position in a negotiation you are also declaring your credibility. If you then backtrack you lose the trust of the party you are negotiating with.
I can can see why you’ve never been in a position to negotiate anything of importance. You are clueless in the extreme. I wouldn’t trust you to be a lollipop man at a school crossing.
The EU are playing with fire. They might see a Cabinet in disarray but they appear not to realise that it’s not the Cabinet that decides the way forward. It’s the wider Tory party that, if anything, is becoming stronger because of the EU’s intransigence.
If the EU doesn’t budge it will be a no deal Brexit, and the EU will be to blame for not negotiating in good faith. The negotiating in good faith is the bit you either don’t grasp or deliberately won’t accept that the EU aren’t doing.
