I think the EU might have taken the political declaration seriously. Walking back on it isn't going to be ideal to get what we want in a trade deal. On the one hand, I would say they government knows this and will blame the EU for the inevitable no deal. However, our complete lack of no deal planning suggests we're arrogant enough to think we'll get what we want. Either way, the circus in charge give absolutely no grounds for optimism and I'd be absolutely amazed if anyone genuinely had confidence in them to do well by us.
