Possibly so!
I do suspect that if the globalist elements of the Labour and Conservative parties (and others) are eventually seen to have conspired to thwart or water down Brexit, then it will be manner from heaven for a populist movement to turn this country's political system and establishment upside down. Powerful enough even to break through the First Past the Post safety net, if the movement even plays by the current democratic rules!
I only half jest. Until now we've only seen parties like UKIP expand and deflate like blisters on wallpaper, but these are nothing more than early warning signals of what can happen when the mass population feels more and more ignored or manipulated by the traditional political establishment, be that national or global.
Right now, we seem to have a situation where a large number if not a majority of MPs seem to be not-so-secretly looking for ways to emasculate Brexit, on the premise that they know best and on the glib assumption that the 52% who voted Leave will have a short-lived grumble and then go back to sleep. They don't seem to appreciate that the agitating factors which led to the Leave vote (and not just immigration by any means) are growing, not subsiding.
It's often argued that calling the Brexit referendum divided the country. Of course it didn't. The divides have been growing for decades, not least the well recognised North/South one. All the Brexit referendum did is allow people to vent that feeling of anger and division in more binary terms than ever before, which is probably why it engaged folk who had previously never bothered to vote.
Quite frankly, if some of the most experienced politicians in the land from all the major political parties are so dim or arrogant as to ignore both the mood music and the quantitative data, then God help them. They're creating the kind of environment that Hitler would have thrived in, and again I'm not sure how much I'm joking!
