Well Jim there may be a case to be made for educating the electorate but who will chose the syllabus, who will teach it, and who will ensure subject matter neutrality. I think you will agree it ain't gonna happen. There is no such requirement for any other election. Wherein lies the difference?
For another referendum I would suggest the following.
1)The required legislation is in place to make the outcome binding on Parliament
2)the electoral commission is made fit for purpose
3)Total transparency is required for all donations
4)all donations to cease 6months prior to voting in order all donations may be vetted
I am sure many other requirements could be added.

We could of course turn many of the arguments here on their head and argue that the remainers were totally illiterate and easily bamboozled by flim flam, and as such should be disenfranchised.

To try to argue the vote should be declared null will cause many to lose faith in the judiciary. Such an argument should be the outcome of parliamentary debate in my view, and the courts should keep well clear.
