We had a referendum the choice was to leave.You have a very narrow view of how democracy works. Are you seriously suggesting that people don't have a right to change their minds?
Had it been to remain there would not have been a word about it. But the EU have form here as we all know. The UK should not be as easily manipulated.
In 30 years if the people want to join the EU, ask them again.
It the politicians were to renege on the people's vote to leave, it would be a very dangerous move for democracy in the U.K. It could lead to never seen before levels of street violence all because the political elite are in hoc to Brussels.
