The problem we have with referendums, is that the UK doesn't adhere to the principle of Government by Referendum.
We adhere to the principle of Government by an elected Parliament. Therefore referendums are only advisory and can't be use to govern the UK by. But some Tory politicians are doing their level best, in trying to BEND the rules to bring about an outcome that's detrimental to the welfare of the UK as a whole.On the basis of Government by Referendum which is a form of government that the UK doesn't adhere to and is not legally binding in the UK.
Why they want to do that, in the face of a parliament that has shown its unwillingness to cooperate on a no deal,seems to be very vague and a need for further investigation as to why, other that the standard bollocks of "taking back control" needs more scrutiny.
Second referendum yes but, one that states: As a principle.That a simply majority is unacceptable and that a qualifying majority is required for a referendum tobe legally binding.
That means a qualifying majority of 70% from the electorate is need to carry the vote. If this principle isn't meet, then any referendum result, should be rejected.
