What do you think people know now that they did not know in 2016 that will encourage those who voted leave to change their vote to remain?
For a start the finding that the way leave campaign was conducted was illegal and if the referendum had been legally binding the leave actions would have resulted in it becoming void.
Also that many of the things said by the leaders of leave campaign have been shown to be complete bollocks, here are a few examples:
1- The 350m sent to the E.U. a week.
^this has been shown to be incorrect, and took no account of the money we received back and other monetary benefits.
2- Getting a deal would be the easiest thing ever, so we don't need to worry about no deal.
^we cant even get past the supposedly easy stage of the negotiations without dangling over the no deal cliff edge.
3- The EU will give us whatever we want
^Well that certainly is not true is it?
4-Turkey joining the E.U.
^not happened.
5- The EU will impose the euro on Britain.
^Nope, we had a veto.
6- We would be forced to join an E.U. rise army.
^Nope, we had a veto.
7- We can't do anything about migration from E.U. to UK.
^We have lots of powers, our government has chosen not to use (largely because of the economic benefit of the status quo).
8 - no harm will come to the economy/there will not be job loses, anyone saying so is just project fear.
^The number of large business and service organisations that have changed their plans is astounding.
Those are a few off the top of my head. There are loads more things people thought leaving the E.U. would solve which has been proven to not be the case.
What Brexit would be and mean was not defined before the referendum. All of the different factions of the leave campaigns had a different vision for Brexit. Everyone voting had their own vision of what Brexit would like. Hence why no one in the government can agree with the way forward. No one really knows what "The will of the people" looked like.
Now we are in a position that has more details of what Brexit is and what it really means, so I think checking back in the public would be a good idea.
If I were to organise the vote I would go for a two question vote, with the first question being a binary should we continue to leave or revoke.
The second would be preferential vote on the achievable leave options, if leave wins the binary vote of the first question.
I think this would give people the say on what Brexit they actually want, instead of the government trying to follow a path of the hardest style Brexit they can get, despite a very close referendum vote.
