But is any of this binding?
Nothing is agreed until everything is agreed, right? So if we dont get the deal we want, if we arent satisfied with the outcome of the next round, we can tear up everything that came before? So the significance of this is principally the statement of intent? Which to be fair is still a big deal, as we have a better idea of where we are heading. A pointless Brexit that leaves us largely in the same situation as we were in before but with less influence is better than a damaging Brexit that pushes business out of the UK and increases the cost of living.
Still, this has surely got more twists and turns to go yet. Let's see what happens in the next stage.
