Caligula May fiddles in Brussels, while time to when we leave burns away. Tsar May with her #Brexit spiritual advisor Rasputin Robbins definitely haven't got the will & certainly not the skill to get any substantial changes. All that is being offered is clarification text which is not legally enforceable. I can't blame the EU for this as all of the numerous commercial deals I have done was like this in the real world, so once the negotiations end (where substantial changes maybe made by both sides) & you have a deal agreed by both parties, only minor changes and clarification is done afterwards. This real world that May & Robbins have no conception or experience of.
The other massive fail by May is when the deal is being negotiated, you keep directors & seniors managers in the loop for two reasons. So they can add feedback & comments, so you get a better deal and as they were involved they buy into the deal. May has made all the managerial mistakes possible on this but also delegating the negotiations to David Davis & Steve Baker and then totally undermined & overriding them with her hidden agenda. She really hasn't got a clue of anything of any real world use. We have all met awfully nice but totally useless people but they are never normally CEOs of major corporations like UK Plc. She has now put the UK in a very awkward position, with far from ideal no deal the only acceptable option. Canada+ which David Davis & Steve Baker were 80% of the way through negotiating with Michel Barnier would have been a much bigger win for both EU & UK with tariff free trade continuing and an easy deal as currently all our standards exactly match.
