The £39 billion was the commitment that's agreed. We are now discussing the withdrawal agreement. It feels like a war the EU simply stonewalls and they are aided by many British politicians who want to stop brexit by undermining our negotiating position. To an extent they have succeeded. I do believe a deal will be done eventually but I feel it will be worse deal than had our politicians worked together for the good of Britain. No chance of that our politicians are a disgrace and completely out of touch with ordinary British people.
You also agreed on a backstop for the Irish border. Pretending you didn't won't make it go away.
Your government has no plausible Brexit strategy, but neither does the brexiteers.
Your politicians lied to you, promising a Brexit that could never be delivered in the real world. No wonder you are angry.
