Brexit: What was wrong with Canada ++?

It occurred to me today whilst basking in Australian summer sun to ask the question: what was wrong with David Davies' negotiated settlement that Ollie Robbins and Theresa May had to come up with the Chequers proposal independently of the DExEU?

Nobody I know has asked that question. If Canada ++ had been negotiated with the EU negotiators, then the EU must have been happy with it?

So why did the team at No.10 replace it? And why was even Chequers further watered down during later talks, apparently without the oversight of Dominic Raab?

Why are the media not asking these important questions? Instead it seems the latest deal is the only one on the table. The deal that locks us into the EU machine indefinitely.

If Canada +++ was on the table before, why is there this insistence that the Ollie Robbins deal is the only one?

All I can assume is that was the plan all along, to make sure we cannot exit the EU ever.

It's nothing less than a coup by the political elite. It's the denial of the democratic will of the people of the UK.

It should not stand.

As a postscript it's interesting to note the reaction of people here in Australia to Brexit. They see our exit from the EU as an opportunity to renew old ties, to right the wrong the Heath government did to the Commonwealth. They see a post-Brexit Britain as an accessible market no longer fenced off by excessive EU tariffs.
