Brexit and Democracy

[Dub]

This thread is not intended to be one to discuss the pros and cons of Brexit. Instead, I'd like to hear opinions on whether or not the UK's current behavior constitutes a violation of their own democratic government.

Here's a beginner's guide to Brexit.

It seems as though there was a lot of fear, anger, and xenophobia in the air when the United Kingdom held their Brexit election which decided they would separate from the European Union.

It was a narrow vote margin, and the campaign was marred with lies and attacks such that even some of the citizens that wanted to be informed about it in order to make a good choice didn't have the skills to separate fact from fiction on the topic.

Once the vote was over, the UK had voted to withdraw.

In working on the details for how this would happen, it suddenly came to many people's attention including leaders that formerly supported Brexit, that they had just gotten themselves into an exceptionally bad scenario.

Now whether they should have known that before convincing people to vote on it or not is an interesting discussion, but the one I am focused on is what happened after the UK realized they had just placed themselves in a disastrously bad spot.

The leaders in the UK began trying to find a way to manage Brexit without destroying their economy.

Seems like politics might be hard and stuff though, because they have yet to unveil the epiphany that will get them to the promised land of economic prosperity that Brexit was supposed to provide.

They were supposed to be gone from the European Union already. They're... not. Politicians and community leaders alike; again even those that supported a Brexit, are dragging their feet to try to find a deal in some way, shape or form. Some are even calling for another election to undo the previous vote.

But the people voted to be gone by now, with or without a deal.

The UK is not gone.

Is this a violation of the principals of democracy?

Why or why not, and what are the implications of that answer?
