Earlier quoted context omitted.
Seems like a wonderful idea, but unfortunately the UK now has both major political parties firmly and irrevocably commited to enforcing the referendum result (whatever that is).
Ok, so I guess that means that all of the democratically elected parties are currently in favor of brexit. That's democracy for you. If you don't like it then people should vote for someone else. The fact that these major parties are committed to enforcing brexit IS the democracy.
Both major parties in the UK are commited to a policy that has around 50% support from the electorate. Because there are long-term issues that make the massive sudden support for an alternative party unlikely, this means that roughly half of the population is left without an effective democratic method of expressing opposition to that policy.
