Would it be democratic to leave the EU at a time when the majority of the population may well be against it ? Put another way - why is it so undemocratic to ask for a second opinion after 3 years time have relapsed along with a better feel for the issues involved ?
You can't ask for a second vote before you've implemented the first. It's that, that is undemocratic.The forthcoming GE, which I assume will happen in November, will be a Brexit referendum. If Remain is that strong, we'll have a Lib Dem government, or perhaps coalition with Labour. But I doubt it personally
