We cross-posted, Iains. My comment about vague generalities was not directed at your post.

When I was a member of Charter '88 one of the demands was for a written constitution. Mrs Thatcher wrote a response that said many of the most despotic countries had a written constitution. On that, at least, she was quite right: such a constitution is not a solution, it is at best a tool, and it is a tool that only works within the rule of law. Claims the judges are enemies of the people does not fit well with calls for a legal framework like a constitution.

And of course it is unfortunately nearly unavoidable to consider the rise and fall of the Weimar Republic when thinking about this. Introduction of a new constitution, reform of the houses and then takeover by a demagogue is not really I model I would want to follow. Again, I believe most Brexiteers would not want that either. SO what do they think can be done to prevent it?
