The next referendum would have to be binding rather than advisory and the referendum based on clear cut options, a concrete deal which could be accepted and triggered the following day, the terms of which can be spelled out in plain English and read by anyone who actually cares and the option to remain for anyone who doesn’t like the terms of the deal.
At least that way campaigns can be demonstrably true or false and people know what they are voting for this time. The fact of the matter is that it was an advisory referendum last time and it’s only because May was desperate to please the hard Brexiters in the party that she lead us off the cliff with “Brexit means Brexit” and invoked Article 50 before we had a fecking clue what any of it meant.
With a sensible government, that referendum should have been nothing more than the first step towards leaving the EU, talks should have been opened in good faith with the EU and a period of negotiation and transparent discussion with the public on what we actually want to achieve.
The reason we are in this mess is because we jumped off a cliff and then had a limited amount of time trying to figure out what we wanted to land on before we actually hit it. There’s absolutely no reason why this shouldn’t have been a 5 or 10 year process and gradual, amicable divorce. The only reason it hasn’t been is because a bunch of elites are desperate to short the pound and keep their offshore accounts out of sight.
